BUTTERFIELD CULTURE IN CALIFORNIA WHEN A home gardener becomes an experienced chrysanthemum grower he usually roots his own cuttings if healthy plants are at hand. A beginning chrysanthemum grower finds it easier to plant cuttings already rooted. PROPAGATE PLANTS WITH HEALTHY TIP CUTTINGS The Experienced Chrysanthemum Gardener What to use for cuttings. Tip cut- tings about 4 inches long are taken some 4 to 6 inches above the base of clumps selected for vigor, variety, and flowering date. A gardener must be experienced in chrysanthemum growing to know what to choose and what to avoid in apprais- ing the mother clumps. The chosen clumps are kept in well- drained soil, safe from freezing, in a location where air temperature favors moderate spring growth. Clumps grow- ing in ground to be prepared for another flower crop are dug up, with the soil in- tact, and are stored in a frame or in a part of the garden where early cuttings can be produced. If verticillium wilt (see p. 19) is preva- lent in the garden, take healthy cuttings from rapidly growing stems above the 18-inch level. At this height from the plant base, cuttings are not so likely to carry the disease. Once verticillium wilt is eliminated from the garden, cuttings can be taken at the usual height from the base of the clump. What not to use for cuttings. Tip cuttings are never taken from the base of a mother clump where verticillium wilt might be present. And they are never taken from woody shoots. These may fail to root well, and are usually far less satis- factory than cuttings from vigorous, suc- culent shoots. Some gardeners make root divisions. The danger that root divisions may not be as healthy as tip cuttings taken from vigorous plants should be recognized. How to plant cuttings. Each cutting is inserted into sand or other rooting medium to about half its length. The leaves on the part of the cutting that ex- tends above ground level are left on to speed rooting. The rooting medium is kept moist but not saturated. Containers used for rooting. If only a few cuttings are planned, root these in individual, shallow pots or even in deep nursery flats. If many cuttings are needed, construct a cold frame. In a cold frame they are usually planted about 3 or 4 inches apart in rows in beds or in benches. Each row is labeled with variety name. Treatment of early and late cut- tings. Early cuttings are best rooted in a heated greenhouse; late cuttings, in beds on ground that will be well drained throughout the rooting period. Tempera- ture is easier to regulate and drainage to control in a greenhouse bench than in a ground bed. Rooting aided by hormone dusts. Hormone dusts may be applied to the base of cuttings. The base is dipped into [i] A flower pot or other small container is used for rooting only a few cuttings. the dust, then tapped to remove surplus powder before being planted. Trade preparations of hormone dusts can be purchased at most nurseries. Length of rooting time. Under fa- vorable conditions, rooting requires about 20 days. The time varies somewhat with variety and with growing conditions. Transplanting rooted cuttings. Some growers prefer to transplant rooted When large numbers of cuttings are set out, it is well to use a standard redwood flat. cuttings to 2 1 /o-inch pots or to plant bands before setting them out permanently. If there is no time for transplanting, then set them directly into permanent location. The Beginning Chrysanthemum Gardener Buying from dependable grow- ers. Until a gardener becomes experi- enced in chrysanthemum growing he will While not recommended by some growers, chrysanthemums may be propagated by division of clumps. The first step in dividing is shown above. [2] find it best to buy cuttings already rooted. These should be bought from growers known to have healthy stock. Cuttings from unknown sources may develop a virus disease and serve as hosts for spread of the disease to nearby plants. Such cut- tings are never satisfactory. Nurserymen selling rooted cuttings usually ship plants bare-root, with the cuttings packed in moist sphagnum moss. Occasionally they ship plants in paper cups with soil about the roots. This prac- tice, however, is not encouraged by hor- ticultural inspectors who find cup-packed plants more difficult to inspect than plants with bare roots. Placing the order early. When buy- ing rooted cuttings, place the order well ahead of planting. This will assure de- livery of the varieties ordered. Most nurs- erymen in filling orders substitute varieties if their supply of cuttings is low. PLANT ACCORDING TO A PLAN The plan of the chrysanthemum garden must meet certain requirements in soil, ventilation, light, space, and irrigation. These requirements are the same whether chrysanthemums are grown outdoors or in a cloth house. The Outdoor Garden Soil preparation. The soil needs to be turned and left open to aerate at least a week before planting. During this time, clods can be broken up and the bed raked and leveled. A deep irrigation is given a few days before planting. When heavy clay soils are very wet they must not be worked. They should dry out enough to crumble well. Then, with proper management and very little tillage, their crumblike structure will be satis- factory. Sandy soils are easy to till. They have limited moisture-holding capacity, how- ever, and usually are deficient in organic matter. Ventilation. Furnish maximum ven- tilation to the chrysanthemum bed. Avoid garden corners with limited circulation of air. In adequate ventilation, the blos- soms will not remain wet during periods of damp weather. Satisfactory air drain- Here, the division is completed. (The soil was removed from the plant to show root growth.) Position of snips shows where plant should be cut back. [3] age is also the primary preventive for Septoria leaf spot and petal blight. Light. Chrysanthemum plants need a limited amount of light throughout the growing season. They will not do well in direct, intense sunlight for the entire day. In early growth their moisture in- take will be badly affected; and in the blooming period their color may be dam- aged. Light must therefore be controlled in some way. Root space. Chrysanthemums should not have to compete with the roots of other garden plants and shrubs. They need a place to themselves and an ade- quate distance from one another. Plant space. This depends primarily upon varietal habits. Close spacing is given to plants that are small-sized; that produce only two or three medium-sized blossoms; or that have an abundance of small, close-hugging blossoms. Close spacing is also used for massive color effects. Wide spacing is given to plants grown for spray effects or for numerous large blossoms. Wide spacing also admits more light and air to the plant and gives room for irrigating, fertilizing, and dusting and spraying. Individual plants in the row are usually set at least 8 inches apart for small-grow- ing varieties and 10 inches for large- growing varieties. Plants grown for mass color effects are set 7 to 8 inches apart and for wide spray effects, 8 to 10 inches. Row space. Plants set in rows are much easier to irrigate and cultivate than plants set at random. Planting beds in the garden are usually 3 feet wide, about 10 to 12 inches apart, with 5 or 6 rows running lengthwise of each bed. Plants set in double rows need a fur- row down the middle and a furrow on each side. Plants set out helter-skelter will have to be watered by hose, sprinkler, or watering can at the risk of damaging stems, foliage, buds, and flowers. Planning for irrigation. In the long summer and fall drought the plants must be watered regularly. This means care- fully studying the planting area, leveling to prevent erosion, and aranging the beds for easy and efficient irrigation (see p. 6) . Planting time. This depends upon the flowering time of the variety and, in some instances, upon the date the flowers are needed. Most varieties are set out during April and into the first part of May. Some gardeners begin to plant as early as March. Too early planting, however, causes plants to grow too tall, with con- sequent hardening of stems before the buds form. Large-flowered varieties are inferior under early planting, some varie- ties growing to a height of 6 feet or more — too tall for chrysanthemums. Plant height and support. Tall plants are tied to stakes, or are supported by wire or possibly by cord stretched be- tween stakes driven in along the row. Small-sized, no. 20 galvanized wire is often used by commercial chrysanthe- mum growers to stretch along the rows, with crossarms of narrow wooden strips fastened crosswise of the beds over the rows. For medium-tall varieties stretch the wires along the row at a height of 3 feet; for tall varieties, 4 feet. Individual, tall plants can be fastened to wires with any kind of tie that will keep them from falling. Large-flowered plants, which may become topheavy during the blooming period, are usually fastened to individual stakes. The Cloth House Occasionally a home gardener decides to become a chrysanthemum fancier and produce large-flowered varieties under cloth. A cloth house is the most practical covering for this type of chrysanthemum growing. Building the house. A cloth house is at least 6 feet or more in height to allow the gardener room in which to work with the plants without stooping. The house frame is usually built of 2- x 3-inch red- wood, with the top and sides covered with [4] Doorway A — Framework with baseboard for cloth house 33'0" x 66'0' Wire Support 60' Double wire twisted to tighten ;- - - 1 H>z-~ ^- _ -~ : r-~Af - ~-—~ - - -~l \Y^~-~ - -" - - "A" - ~ ~s --"-"1ll:--^- _ r-:-:-A Anchor -i-I-Uz-Vf-"-^ B — Method of anchoring posts Sometimes a home gardener becomes a chrysanthemum fancier. Then, he will find the cloth house the most practical type of cover. [5] cheesecloth that either is sewed together or is fastened on in separate strips. The cloth is held in place by strips of plaster lath nailed to the frame. Reinforced in this way the cloth house is resistant to all but a very heavy wind. The door open- ing can be a wooden frame, with either a cloth-covered, wooden-frame door, or a piece of cloth left loose to be fastened back or to hang across the opening. The cheesecloth should be of fine mesh —20 x 24 or 24 x 28— which is very satisfactory for shading plants during the growing season. Planting. This is done in rows, as in the garden, for easier watering and cul- tivating. The planting beds are 3 feet wide, about 10 to 12 inches apart, with 5 or 6 rows running lengthwise of each -bed. IRRIGATE TO ADJUST HUMIDITY, TEMPERATURE, AND SOIL MOISTURE Regular and Deep Irrigation Chrysanthemum growth should never be checked by insufficient soil moisture nor water-logged by soil maintained at full water-holding capacity. Irrigation should be frequent enough to produce steady growth, with leaves kept in suc- culent condition. Type of irrigation. Furrow irriga- tion, wherever practicable, is recom- mended. The furrows are 3 to 4 inches deep and, because they tend to fill with suckers, are approximately 6 inches wide Basin irrigation for an individual chrysanthemum plant. to carry sufficient water for a thorough irrigation. If the plants are in beds slop- ing lengthwise, it may be necessary to dig cross-furrows that can be filled with water at irrigation. If the plants are in contour position on slopes, they should be furrow-watered by the double-row system. Basin irrigation may be used around individual plants. The basins are formed far enough away from the plant not to disturb the roots and deep enough to per- mit thorough watering. Overhead sprinkling is rarely advis- able. The weight of water on foliage often bends unsupported stems; and water striking flowers soon injures them, as is easily seen when petals remain wet for any length of time during rainy periods. If overhead sprinkling must be used, sup- port the plants and try to avoid wetting open flowers. Flooding is successful only on level-surface beds. How often to irrigate. Irrigation may be necessary twice a week during the warm summer months and only once a week in cool weather. The interval be- tween irrigations depends somewhat on dryness of air and on temperature, but more on diminishing soil moisture. When rains begin, the plants may need little or no irrigation. The object of irrigation is to saturate all of the soil in the root zone; then to withhold water until the plants use most of the available moisture. The exact time [6] is usually indicated by both plant and soil. The leaves of a plant properly watered and fertilized will be large, healthy, and succulent. Those of a plant insufficiently watered will turn dull green then gradually wilt. If insufficient soil moisture continues, older leaves will de- cline prematurely and dry. How deep to irrigate. Water should run long enough to soak all of the soil in the root zone, which is usually one foot or more deep. Place a hose at the upper end of the furrow and let the water run until the furrow is filled or the water has had time to soak down to the proper depth. Importance of Salt-free Water Use water almost entirely free of sol- uble salts. Well water high in soluble salt should not be used ; it will stunt the plants and cause decline. Some people are forced to buy water that is salt free rather than to use local well water that is too high in salt. If water reaches the danger point in salt content, irrigate heavily at each watering to help wash excess surface salt down below the roots. Indication of too much salt. There is no simple test for determining salt con- tent. Perhaps the best indication of too much salt in soil or water is the severe stunting of plants. FERTILIZE IN GROWING SEASON FOR HIGH-QUALITY FLOWERS Chrysanthemum plants are called gross feeders. They can exist and produce flow- ers on soils of only medium fertility, but unless they receive generous amounts of nitrogenous fertilizer during the growing season their flowers will be of poor qual- ity. This is especially true of large- flowered varieties and less so of small- flowered varieties. Soil Deficiencies Most California soils become deficient in nitrogen unless they are given manure or some other form of organic or inor- ganic fertilizer. Only occasionally are chrysanthemum-growing soils deficient in phosphate, and rarely in potash. Nitrogen deficiency. This shows in lack of succulence in stems and leaves. This symptom is not conclusive, however, because it is also a symptom of certain diseases. Only by adding nitrogen to a soil can the grower be certain of nitrogen deficiency. Phosphate deficiency. Poor plant growth and pale-green leaves that are a darker green near the petiole indicate phosphate deficiency. Leaves may drop from the base of the plant upward. This deficiency is corrected with steamed bone meal or superphosphate. Potash deficiency. This is indicated by weak plant stems and poor growth. Leaves may be mottled green with brown- ing at the edges. Here, again, application of the deficient chemical is the only test of deficiency. Nitrogenous Fertilizers Both organic and inorganic nitrogen fertilizers, or a mixture of the two called mixed fertilizer, are used as adjustments. An organic fertilizer, such as fish meal, can be supplemented with an inorganic fertilizer, such as ammonium sulfate. Manufactured sewage sludges are used, but to a limited extent because the supply is not plentiful and the cost is high in proportion to the amount of nitrogen present. Liquid nitrogen fertilizers have been run in irrigation water, but scatter- ing the dry fertilizer along the row is a more commonly used practice among amateur gardeners. Amount of fertilizer to use. An organic fertilizer containing 6 per cent nitrogen can be used at the rate of 2 to 4 pounds or more per 100 square feet, two [V] or three times during the growing season. An inorganic fertilizer containing 20 per cent nitrogen can be used at the rate of 18 ounces per 100 square feet. For a light application this amount may be reduced and used more often. A mixed fertilizer containing 6 per cent nitrogen can be used at the rate of 4 pounds per 100 square feet. Several light applications may be better than one heavy application. Weak liquid fertilizer may be used to force plants for very large flowers. This is applied weekly until color begins to show in the flower buds. How to use fertilizer. Organic fer- tilizers are used when the soil is heavy or is low in organic matter; commercial inorganic fertilizers, when the soil needs nitrogen only. The fertilizer is then car- ried down 6 inches or more to the feed- ing roots with the irrigation water. Strong fertilizers must not come into con- tact with the leaves of the plant. Testing for right fertilizer. A grower may not know which fertilizer will give the best results. He can experi- ment by laying out a test plot where dif- ferent fertilizers are used, and a check plot where no fertilizers are used, then compare the results. Flower quality un- iailingly indicates the comparative value of fertilizers. Correctly fertilized plants produce flowers of larger size and better color, and have stronger stems and greener foliage than plants that are not given fertilizer. Green-manure fertilizer. Growing a green-manure crop to be turned under is impractical. Often, at the very time the crop should be turned under, the chrys- anthemum seedlings are ready for plant- ing. REGULATE GROWTH FOR DESIRED EFFECTS Growth is regulated by stopping or pinching-back, disbudding, restricting side shoots, training to cascade form, and shading for early bloom. Stopping or Pinching-back This practice must be followed with great care. Either pinching back too little or too much will result in low-quality flowers. The technique is the same for all sizes and varieties of chrysanthemums. The difference with each variety and size is in where to pinch back. How to pinch back. This is done with the tips of thumb and forefinger. The tip growth to be removed is usually close to a bud in one of the leaf axils. For young plants. A young plant usually is well established in about two weeks after it is set out. Begin to pinch out new tip growth to encourage branching. For medium-sized varieties. When the young plant has developed three or four eyes or buds in the axils of new- growth leaves, pinch out the growing tip. The remaining buds then can grow. Select three or more of these new basal shoots to form the flowering stems. Tests have shown that a plant left with two stems will produce flowers as large as a plant with only one stem. A plant left with three stems should produce flowers of adequate size if given sufficient water and fertilizer. For tall-growing varieties. Some vigorous and tall plants will need pinch- ing-back several times before the stem is allowed to continue growth for flower- bud formation. Pinching-back must be done carefully on tall-growing varieties. Excessive pinching-back may delay flow- ering and decrease flower size; insuffi- cient pinching-back may result in very tall, hard stems, and low-quality flowers. The interval between the last pinching- back and flowering is about 2% months for late varieties and as much as 3% months for some early varieties. For early pompon varieties. Shad- ing cloth is often used to bring about early August flowering of Gold Coast, Irene, Pinocchio, and Dark Pink Jewell. [8] Under shading cloth, pinching-back should not continue after the latter part of April. Disbudding The terms first crown bud, second crown bud, and terminal bud can con- fuse the beginner. The illustration below shows where these different buds are lo- cated on the plant. The first crown bud is the first bud to form at the tip of a stem. The second crown bud forms just below the first crown bud, at the tip of new growth. This bud forms on only a few varieties, such as Alice Benson and Thomas W. Pockett. The second crown bud some- times makes a better flower than the first crown bud. The terminal bud will ap- pear in time if the plant is allowed to continue its growth with the first and second crown buds remaining. Terminal buds develop last. First and second crown buds. If the first crown bud is saved, no terminal buds are allowed to develop. For instance, if the first crown bud is saved in a par- Terminal bud Here, a plant that has made good growth is pinched back to encourage laterals. ticular variety, such as Clara Curtis, then all other buds are removed as they ap- pear. If the second crown bud is saved and the first crown bud is removed, then all Lateral terminal bud Terminal bud Typical bud growth on a chrysanthemum, showing both terminal and lateral buds. Use this photograph as a guide for disbudding. [9] later buds are removed. There are many varieties where both of the crown buds are removed and terminal buds are se- lected, as in Ambassador, Indianapolis, and Orchid Queen. If anything should happen to the terminal bud saved, then the stem might as well be removed, be- cause no more buds will form at the tip. In some instances the choice between crown buds and terminal buds is deter- mined by bloom date. For example, a delay of two weeks with W. H. Waite will often give a more brilliant color; therefore, the terminal bud might be bet- ter than a crown bud. In some varieties the crown bud aborts or is so small that it will not make a good flower. Nothing short of actual experience will indicate whether crown buds or terminal buds should be taken. Terminal buds. These are produced in clusters of a few to many. On small- flowered varieties no attempt is made to select buds or to disbud; many people prefer the beautiful sprays produced on all of the small-flowered varieties. The plants will develop sprays of both crown and terminal buds, but the mass of ter- minal buds will give the desired cluster effect. A few large pompon varieties are disbudded, as are some large anemone varieties and a few large singles. Considerable surplus side growth will develop after disbudding. It may be de- sirable to check the plants occasionally to remove this side growth, especially the very late side buds growing low on the stems. Unwanted late suckers should also be removed. How to disbud. Disbudding, like pinching-back, is done with the tips of thumb and forefinger. The unwanted bud is broken off close to where it joins the stem. Try not to leave a stub in the leaf axil. A pointed pencil can be used to break out a small bud. Chrysanthemum plants should be gone over repeatedly for several days or weeks to complete the work of disbudding. While bending over the plants, avoid breaking tender selected buds. A little experience will teach how to break un- wanted buds gently, close to the main stem so that no evidence of careless dis- budding shows later. Restricting Side Shoots Most chrysanthemum growers select three of the best stems on a plant for late flowers. They remove all other basal shoots. Only occasionally is a single stem per plant left — this usually by commer- cial growers. How to remove shoots. These are never torn from the plant. Tearing or pulling them off leaves a ragged wound; tearing can even peel the surface far down the stem. A shoot is cut out with a sharp knife, or pruning shears, or by pinching out with thumb and forefinger. Treatment of different varieties. On small-flowered varieties only part of each stem is left to blossom. Remaining side shoots die out from natural shading; others can be removed where necessary. More stems are left on an extremely vigor- ous plant, such as Alex Stribling, than on a weak plant, such as Bobette, whose size is not improved by thinning or dis- budding. Few gardeners would attempt to disbud a single variety, such as Mrs. Bucking- ham, or to spend much time thinning the plant, because the size of flowers and sprays would be about the same by either treatment. This is also true of the smaller pompons and many of the anemone va- rieties. The larger, spider varieties need well-planned restriction of side shoots, especially for exhibition blooms. Training to Cascade Forms A few home gardeners who have time and patience train chrysanthemum plants for cascade effect. The technique, usually practiced by fanciers for nursery or flow- er-show exhibit, must be carefully fol- lowed or should not be attempted. Vigorous varieties with long, flexible stems are trained best into large cascades. [10] Less vigorous varieties with moderate- length, slender stems and many flowers, are best for small cascades. A spider variety trained to cascade form is shown below. Table 4 lists several varieties used for cascades. Varieties with only a few flowers do not train satisfactorily, especially when these few flowers are close to the base. Cascade forms. There are several satisfactory cascade forms. The heart shape is the most popular. The fountain also is well liked, and occasionally a double cascade is seen at flower shows. The thin or narrow cascade, occasionally used, is not popular. Pots and potting mixture. A terra cotta pot, a flower jar, wooden tub, or box, which can be kept at elevation dur- ing the training period, are used for planting. The starting pot for the young plant is usually 4 to 6 inches in diameter. As the plant roots grow to the walls of the container, the plant is transferred to a larger container. This process may be repeated two or three times. The final potting should be completed by about the middle of August. At this time the plant may be in a 10- or 12-inch container. The transfer from one pot to another must not disturb either roots or top growth. If the solid earthen form encas- ing the roots cannot be easily lifted from the pot, the pot should be cracked, spread apart, and the form removed. The potting mixture can be 2 parts fertile loam soil, 2 parts well-rotted oak leaf mold, and 1 part well-rotted steer manure. Exposure for plant. A plant in train- ing is placed in a warm, southern ex- posure, protected from wind and rain. The plant container is elevated on a bench or shelf, at least 3% to 4 feet from the ground so that the final cascading branches will not touch the ground. In a Small pompon, such as Nuggets (above), and spider varieties, such as Sarah (below), can be trained to cascade form with beautiful effect, as shown here. greenhouse, set the pot near the front of a bench. With adequate water and fer- tilizer the plant should grow vigorously. Length of training period. The planting date for cascade forms is gauged somewhat by variety. However, the young plant or seedling is usually set out in the 6-inch pot in early May. The exact dates of training completion vary according to variety and growing conditions, but by September 15 the final pinching-out of the plant should be com- pleted. The training technique outlined here holds true for all cascade varieties regardless of varietal dates in planting or flowering. Steps of training. When the plant is 5 or 6 inches tall, the top is pinched out. This encourages branching at the base. From the branching growth is selected the endmost shoot to be used as the main leader. As growth continues, or in about two or three weeks, begin to pinch out all new side growth at every second or third leaf joint until the first of Septem- ber. After that date do not pinch out any more side growth. When the plant is about 12 inches tall, frame-training can begin. Insert a frame- work of 10- or 12-gauge galvanized iron wire to which the stems will be tied. A single wire, 3 feet long, will be adequate at first, but, as training continues, addi- tional wire, 4 feet long, will have to be inserted. Commercial plant ties are very useful for fastening stems to the wire supports. The main leader is lowered gradually as the wire support is bent down farther. One by one the laterals also are bent. Beginning 5 inches above the surface level, they are tied to training wire that is bent at an angle of 45 degrees. This gradual downward bending of all wires continues until middle September, when the plant should be almost horizontal. The stems should still be flexible. The lateral stems, whose buds were pinched out repeatedly, are now ready to be spread out in equal numbers on either side of the main leader to produce a well-balanced plant. The still-flexible stems are tied into position and will gradually form the planned shape of the whole plant. Cascade plants tend to start blooming at the tip, ahead of side or lower branches. This tendency can be changed by com- pleting the pinching-out of basal laterals around the first of September. The broad- est part of the plant will be completed about five days later; the midsection in another five days, or by about September 10; and complete pinching-out of the tip will be accomplished by the middle of September. This gradual completion of pinching-out from base to tip over a period of about 15 days encourages an even maturity of flowers over the entire plant. The flower buds forming after the last pinching-out will weight the stems and aid the wires in bending the plant down- ward. Bending usually is completed by the time flower buds show color. At that time all stems should point downward, with side branches hanging in final form as a fan. Shading for Early Bloom Shading is a technique used by some gardeners and commercial growers to produce very early bloom. Its effect on size and quality of bloom has been tested by growers in central California; more tests are needed to determine its full suc- cess with chrysanthemums in other areas. What shading does. It limits day length to 12 to 13 hours for approxi- mately 40 days during June, July, and August. The exact number of days is gauged by varietal differences. Correctly done, shading can advance the bloom date by 25 to 56 days. Shading not only regulates light inten- sity; it also conserves moisture in soil and air. The increase in humidity under cloth tends to reduce water requirements. It raises the temperature about 1 to 3 degrees Fahrenheit, which is satisfactory [12] to some varieties but unsatisfactory to those that do not form buds in tempera- tures below 60° F. Amount of light needed. Duration of light rather than variation in normal light intensity regulates the time of flow- er-bud formation. Anything above 4,300 foot-candles of light will probably be adequate for the 12 hours of daylight allowed to shaded plants. The light under greenhouse conditions varies between 4,300 and 4,400 foot-candles. The light under black shading cloth is cut to less than 50 foot-candles. If the weather is overcast during the normal shading period, shade only on alternate days; otherwise failing plant strength will cause the stems to remain short. Unless the plants are adequately watered and fertilized and given sufficient light, air humidity, and ventilation, this marked variation in shading technique will leave the weakened plant highly sus- ceptible to fungus troubles. Effect on bud formation. Shading tends to cause terminal rather than crown buds to form. This is satisfactory for those varieties on which a terminal bud is selected. But for such varieties as Alice Benson, Clara Curtis, and Unaka, on which a crown bud is selected, shading may not be desirable. Effect on bloom size and quality. This was tested by the Ohio Agricultural Experiment Station on such varieties as Ambassador, Betsy Ross, Chieftain, Friendly Rival, Golden Bronze, and In- dianapolis. The experiment indicated that shading did not materially affect size and quality of bloom, whether two or three stems were left on a plant or only one. Varieties responding to shading. Early midseason varieties respond best to shading; they require about 36 days of shade. Many of the pompons respond to shading. They require 36 to 40 days or more of shade, depending on the variety, with the cloth removed when the buds begin to show color. Large standard varieties will probably need shading for approximately 40 days in June and July. Very good results can be expected in about 40 days for such large varieties as Ambassador, Hilda Bergen, Indianola, Silver Sheen, and Snow White. Shading should continue with these varieties until the flower buds are showing color. The harvest season for both large- and small-flowered varieties can be extended by planting at intervals of one to two weeks, rather than all at one time. Hours of shading. The cloth is pulled over the plants at about 5 p.m. daily. It is removed the next morning between 7 and 8 a.m. Treatment of cloth. Black shading cloth comes in bolts of 100 yards, one yard wide. Various grades are sold, but a black sateen known as Windsor cloth no. 375, with a mesh of 64 x 104 to the inch, proved best in the tests reported by the Ohio Agricultural Experiment Station. This cloth admitted only 1.9 foot-candles of light, or 0.04 per cent of the total light. Shading cloth is usually sewed together to make 5- or 10-foot strips. For tall vari- eties, the top shading cloth should have a side clearance of about 5 feet, and an allowance of 5 feet for side curtains. Al- lowance must also be made for some sagging of the cloth between supports. CLASSIFICATION VARIETAL TABLES Chrysanthemums are classified according to certain characteristics of their blooms. A description of the classifications, together with illustrations of some, begins on page 23. Tables listing a great many varieties and comments on each begin on page 30. [13] PRODUCE NEW VARIETIES BY SEEDING AND SELECTING BEST OF SEEDLINGS The term new variety usually means a new, cultivated form developed from seed. Only occasionally does it mean a new variety accidentally appearing in the garden by mutation. About three years of testing are needed to determine the nature and worth of any new seedling variety. Only then, and after it has met the approval of national chrysanthemum organizations and leading fanciers, is it named. The name chosen is one not yet used for a chrysanthemum variety. The simple manual techniques of seed- ing, planting, pollinating, and cultivating are easier to learn than the more difficult details of line-breeding. Line-breeding calls for a knowledge of good parent stock and of the desirable inheritable charac- teristics from such stock. New Varieties by Line-breeding Good parent stock. The experienced breeder in time learns which parents give rise to desirable seedlings. He also learns which characters are inherited in pure form from each parent. Line-breeding may be used to determine the nature of inheritance. Desirable inheritable character- istics. These are good stem, color, size, and flower form. Each of these charac- teristics must be considered when inspect- ing the inherited characters in seedlings. Producing the seedlings. Seed is produced on single-stem plants grown in the garden or in pots in a greenhouse. Only a small amount of fertilizer is needed in either type of planting. The flowers of garden plants are covered with a cellophane bag to help exclude foreign pollen and to lessen danger of early rain damage. The flowers of greenhouse plants also are covered with a bag, to exclude foreign pollen that might accidentally be introduced by insects. Before any pollen is shed, both petals and stamens are removed from each flower. The pollen from the desired parent is then introduced when the pistils are receptive, that is, when the pollen grains are sticking to the stigma. Records of both seed and pollen parent are kept. . Seeds ripen in about six weeks; they are sown immediately in any good, light soil mixture in air temperature of 60° F. When the seedlings become crowded, they are transplanted. They should flower the first year. New Varieties by Mutation Occasionally a new color form will ap- pear on a plant as the result of mutation. This sudden and permanent change in a plant or on part of a plant may be a desirable mutation that can be repro- duced true to the new form by rooting stem cuttings in the usual way. Selections are made at flowering, when it is possible to see whether the new color or form of the plant is uniform. Any plant not conforming to the new color or form should be discarded. Experiments in Chrysanthemum Breeding There are almost no references on chrysanthemum breeding. One, coau- thored by Elmer D. Smith and Alex Laurie, and now out of print, is listed among the references in this circular. In earlier years, Mr. Smith of Adrian, Michigan, introduced many varieties that are still popular. In time, reference material may result from experiments being conducted by the United States Department of Agricul- ture at the Horticultural Station at Belts- ville, Maryland, and by the universities of Chicago and Minnesota. Experiments conducted by the Oakland, California, Park Department have produced several new varieties. The Park Department has held a chrysanthemum show annually since 1940. [14] CONTROL PESTS AND DISEASES Several pests and diseases attack the chrysanthemum, sometimes with very damaging results. Neither all of the pests nor all of the diseases described attack in one garden or in one locality, but, because they all do occur in the state, growers should be able to recognize them and know about their control. To begin yearly with healthy cuttings and attempt to plant in uninfested soil is probably the best means of controlling both insects and diseases. When using any chemical spray or dust for either pests or diseases carefully fol- low the directions printed on the container. This will assure more successful results and will serve to warn the user if the chemical is poisonous to human beings and animals and must be handled with unusual caution. Pests The most important pests attacking the chrysanthemum are aphids, caterpillars, chrysanthemum gall midges, ground mealybugs, leaf miners, spider mites, and thrips. Aphids. These include the chrysanthe- mum aphid (Macrosiphum sanborni) , cotton aphid (Aphis gossypii) , green peach aphid {Myzus persicae) , leaf-curl plum aphid {Aphis helichrysi) , and thistle aphid (Anur aphis cardui) . Aphids or plant lice attack either in the garden or under cloth and glass. Their damage to the plant is in a mottling of the leaves or flowers and an accumulation of honey- dew on the plant. Begin control as soon as aphid colonies appear. Control can be complete with weekly applications of any one of such insecticides as nicotine sulfate, benzene hexachloride, lindane (which is the pure gamma form of benzene hexachloride), pyrethrum, and light oil emulsions. Sev- eral new products being tested show promise. Some of them may become sub- stitutes for older products that have been used for many years. Caterpillars and other leaf-eating insects. These include the greenhouse leaf tier (Phlyctaenia rubigalis) , checker spot butterfly (Euphydryas chalcedona) , orange tortrix {Argyrotaenia citrana) , and sometimes the woolly bear caterpillar of the acraea moth {Estigmene acraea) . Caterpillars occasionally attack opening buds and late-season flowers, but with limited damage. If only a few such cater- pillars appear, eliminate them by hand picking. In control, use a 50 per cent wettable DDT at the rate of about % ounce to a gallon of water for all leaf-eating insects except the woolly bear caterpillar and the orange tortrix. Use pyrethrum sprays or dusts in repeated applications to destroy these two pests. Chrysanthemum gall midges (Di- arthronomyia chrysanthemi) . This pest can seriously damage leaves and growing tips of chrysanthemums, especially if plants are not started from healthy cut- tings each year. The adult midge lays Distortion of this leaf was caused by the chrys- anthemum gall fly or midge. [15] clusters of tiny red eggs on the leaves or young tips, and the small maggots that hatch soon penetrate the tissues to pro- duce cone-shaped galls or raised bumps on leaves and stems. A serious infesta- tion will stop all plant growth and deform remaining stems and buds. This pest is more serious in shade than in sunlight, either in the garden or under cloth and glass. Highly susceptible varieties are White Mensa and Golden Mensa. Prevention is the best method of con- trol. Plants started yearly from clean tip cuttings will probably not be attacked. Control with chemicals must begin early to be successful. Benzene hexachloride gives satisfactory control. Lindane is not so satisfactory. Allow % ounce of 10 to 12 per cent gamma isomer benzene hexa- chloride to 3% gallons of water. Ground mealybugs (Rhizoecus fal- cijer) . This pest is much smaller than the common mealybug, such as Baker's mealybug. It lives on the roots of her- baceous plants, including the chrysanthe- mum. If the roots of a plant become infested, yet the variety cannot be re- placed easily, take off healthy tip cuttings and root these. If these healthy cuttings are planted in new soil uninfested with the pest, the roots will not become in- fested. Again prevention is the best method of control. Starting with healthy cuttings yearly and planting in a new garden loca- tion is best. If the pests appear, expose them to dehydration by cultivating the beds. Ground mealybugs cannot endure exposure and consequent drying-out. Before planting in an area known to be infested, cultivate the soil for about six weeks to dry it out. This may rid the bed of all pests. For greenhouse cultivation, sterilize potting or bench soil before planting. Control by spray is not successful around the roots of infested plants. Im- planted beds can be fumigated with ethy- lene dibromide or dichloroethyl ether to destroy any insects present. Leaf miners. The chrysanthemum leaf miner {Phytomyza atricornis) , the burdock leaf miner {Dizygomyza macu- losa) , and perhaps other species, such as Agromyza setosa, may attack chrysanthe- mum stems and leaves. The small maggots tunnel through the surface tissues and discolor the affected parts. Winding mines or blotches just beneath the sur- face tissue indicate leaf miner damage. The adults may also puncture the tissues. Severe injury makes the foliage un- sightly ; it may also cause premature leaf drop. For control, some of the new insecti- cides, including chlordane, benzene hexa- chloride, and lindane, are promising. Al- low % to 1 ounce of actual chlordane — preferably in wettable powder form — to 3% gallons of water. Benzene hexachlo- ride and lindane may be used at the rate of V2 ounce of 25 per cent gamma isomer to 3% gallons of water. This spray should be effective if applied at intervals of from one to two weeks. Spider mites (Tetranychus bimacu- latus) . The common red-spider mite or two-spotted mite, found on many plants, is sometimes a pest on chrysanthemum leaves. It increases very rapidly under cloth or glass. This mite forms a small, thin web on leaves and flowers. It hides mostly on the underside of the leaves. By sucking the juices, it drains the green color, which leaves a blotched effect. The leaf is then weakened. Control of the two-spotted mite with sulfur dust is not very effective. A trade product known as Aramite is very effec- tive. It is available directly from chemical supply companies but not usually avail- able in small-sized packages from garden supply houses. A combination spray packaged in small amounts for use in the home garden is planned by a large chemi- cal company in California; the two mate- rials to be used are malathon and lindane, which should control such chrysanthe- mum pests as mites, aphids, and cater- pillars. [16] Thrips. Several kinds of thrips may attack chrysanthemum plants, includ- ing flower thrips, onion thrips, chrysan- themum thrips (Thrips nigropilosus) , banded greenhouse or sugar beet thrips (Hercinothrips femoralis) , and statice thrips [Haplothrips leucanthemi) . These small, rasping insects attack tender growth, where they produce scar tissue. In severe infestations all new growth may be stopped. Control by several new insecticides is prompt and effective. DDT, benzene hexa- chloride, and lindane sprays or dusts are very effective. Start control before dam- age is severe. The same amounts of DDT, benzene hexachloride, and lindane used to control leaf miners, midges, and leaf- eating insects will also control thrips. Miscellaneous insects. Chrysanthe- mums are attacked by other insects, such as plant bugs, leafhoppers, and whiteflies. Plant bugs (Lygus bugs) occasion- ally damage both flowers and leaves. Where they feed at the base of a flower, that point ceases to develop and growth becomes one-sided. Where they feed at the young leaf buds, the leaves show a lacy perforation. Control by growing the plants under cloth or glass is fairly effective. Chemical control is by spray, with 50 per cent wet- table DDT at the rate of % ounce to a gallon of water. Leafhoppers occasionally are trou- blesome. These may be checked by the same proportions of 50 per cent wettable DDT spray used for plant bugs. Whiteflies sometimes spread to chrys- anthemums from nearby host plants. Control by a spray of DDT and summer oil is effective. Oil combinations with nicotine sulfate or pyrethrum give fair control. Diseases Diseases to which chrysanthemums are susceptible are aster yellows; basal rot of cuttings; Deuterophoma disease; leaf spot; petal blight; powdery mildew; rust; spotted wilt; verticillium wilt; and virus stunt. Aster yellows. This virus disease, also known as Yellows, may attack chrys- anthemums. Infective leafhoppers spread it from diseased host plants. The pest may be excluded to some extent by cloth or glass. Since there is no cure or control, select cuttings from healthy plants only. Basal rot of cuttings. Basal rot of soft green cuttings is seen occasionally in propagating benches. It causes serious losses from January to April if cuttings are kept very wet at a cool temperature. Sclerotinia sclerotiorum, as well as species of Fusarium and Pythium, may be involved. Good ventilation and small amounts of moisture during rooting are important preventives. The best control is to take cuttings only from healthy plants and root them in a sterile medium, such as vermiculite. Rooting under glass or muslin rather than in dense shade re- duces the danger of basal rot. Treating the base of cuttings with Fer- mate has been attempted. Results were spotty, perhaps because too many differ- ent organisms were involved, some of which are effectively controlled by Fer- mate and others not. Deuterophoma disease. This slow- acting disease is caused by a fungus that invades the vascular system of the plant. The fungus is soil-borne, and once it in- fests the soil it will attack even clean cut- tings. Affected plants often bloom earlier than healthy plants, and develop a stunted appearance similar to that caused by virus stunt. Healthy plants set into in- fected soil will produce normal flowers the first season; cuttings taken from the plant, however, will produce badly stunted plants the second season. The only possible control for Deutero- phoma disease is to use disease-free cut- tings, and even these can be attacked by soil-borne infestation. Leaf spot. Septoria leaf spot is caused by two different species of Septoria: S. chrysanthemi and S, obesa. The form S. [17] Flower blight here was caused by Botrytis cinerea (see petal blight, below). The healthy flower at extreme right is shown for comparison. (Courtesy Department Plant Pathology.) chrysanthemi produces dark leaf blotches up to % inch in diameter. Lower leaves are affected first. The diseased leaves soon die, but may continue to cling to their stems. S. obesa produces the same general symptoms. Septoria leaf spot is primarily a green- house trouble. It should not occur if ven- tilation is adequate and if irrigating is done without splashing. If it does occur, it can be checked to some extent by spray- ing with Parzate, Fermate, or Dithane D-14. Petal blight. The fungus Botrytis cinerea causes petal blight. It may be ex- pected during cool weather when exces- sive moisture remains on flower heads for several hours. Among the varieties sus- ceptible are Arcadia, Jewell, Nellie Pock- ett, White Mensa, and Yellow Dot. Control is by preventive measures. Plan the chrysanthemum beds for ade- quate ventilation so that excessive mois- ture cannot remain on the flowers during cool, wet weather. Under cloth, plants will be less likely to suffer blight if intermit- tent openings are left in the roof. There will be far less humidity during rainy weather under cloth ventilated in this way than under a solid cloth roof. Powdery mildew (Erysiphe cichora- cearum) . This white fungus often attacks the leaves of plants, grown in shady spots, during the latter part of the growing sea- son. The leaves are covered with a white mildew fungus that resembles rose mil- dew. Control is with liquid-sulfur sprays and sulfur dusts. A 1 per cent lime sulfur solution and a wettable sulfur spray have also been used. Follow the directions given on the containers. Rust (Puccinia chrysanthemi) . Rust fungus blights the leaves and in time covers the affected foliage with dusty, brown spores. The best control is to destroy all badly affected plants and to start yearly with disease-free new cuttings on ground where the fungus has not occurred. - 1 ':■' V.' Chrysanthemum rust pustules on the backs of leaves. (Courtesy Department Plant Pathology.) [18] Control tests conducted in California in 1949 indicated that rust may be con- trolled with either Parzate or Dithane D-14 applied at weekly intervals. Parzate is used at the rate of % ounce to a gallon of water. Dithane D-14 is applied at the rate of about % fluid ounce to a gallon of water. Zinc sulfate is added to the Dithane D-14 spray at the rate of about % ounce to a gallon of water. A spreader or sticker is added to either spray material. For example, if du Pont Grasselli Spreader-Sticker is used, the rate is 1 part to 1,000 parts of spray. Any spreader should be used according to instructions on the container. Spray- ing should begin at the first appearance of rust spots, with the spray completely covering the under surface of the leaves. Verticillium wilt (Verticillium albo- atrum) . This fungus is not limited to soils in which chrysanthemums grow. It has often severely injured field crops, such as cotton, tomatoes, and strawberries. Leaves of chrysanthemum plants at- tacked tend to wilt at the margins then turn brown. They die progressively up- ward from the base of the plant. If blos- soms are affected, the outer petals look burned. Verticillium wilt can be suspected when many dead leaves appear near the base of a plant and dying leaves spread upward. A cross-sectioning of the stem near the ground may show a discoloration or browning of the woody tissue, also a symptom of the disease. Visibly sick plants showing stunted growth are usually considered beyond recovery and are discarded. Sometimes, however, a grower may attempt to save a severely infected yet valuable plant for its cuttings. He may hope to control the wilt to a small degree by growing the plant with a scanty amount of soil rnoisture. This is a drastic, emergency treatment, recommended only for a valu- able plant. When the time is ready for cuttings they should be taken from the plant only at the 18-inch level. A temperature of 60 to 75° F is most favorable for the disease, but if a plant is already infected, the fungus may per- sist beyond this range of temperature. Preventive rather than control meas- ures are used with verticillium wilt. Avoid planting chrysanthemums on the same soil continuously for several years. To do so leads to the soil's increased sus- Effect of verticillium wilt on leaves of chrysan- themum (above) and on stems (below). The disease is caused by a soil-borne fungus. (Cour- tesy Department Plant Pathology.) 119] ceptibility to the disease, especially if the soil is kept fairly moist and at a tem- perature of 60 to 75° F. For greenhouse planting, sterilize the soil used in pots or beds. A limited amount of soil can be sterilized with 1 cc of chloropicrin to a gallon of soil. Some people use up to 7 to 10 cc of chloro- picrin to a cubic foot of soil, although the smaller amount has proved adequate in central California. For garden and field planting do not use soil where susceptible crops, such as cotton, tomatoes, and strawberries, have grown; and do not use soil in which ver- ticillium wilt has actually appeared. If space is limited, and the same soil must be used yearly, select varieties that are resistant. The grower should therefore know what varieties are resistant and what are susceptible. A few varieties are listed here according to whether they are : (R) resistant; (M) moderately resistant; and (S) susceptible. Large commercial and exhibition varieties: Albatross (S) Ambassador (M) Anaconda (S) Apricot Queen (M) Betsy Ross (R) Bronze Frick (S) Bronze Orchid Queen (S) Detroit News (R) Friendly Rival (R) Garnet King (R) Gladys Pearson (S) Good News (R) Helen Frick (S) Hilda Bergen (S) Indianola (R) Ivanhoe (M) J.

Bowes (M) Monument (R) Orchid Queen (S) Penrod (S) Pink Turner (S) Silver Sheen (R) Snow White (M) Thanksgiving Pink (R) William Turner (S) Yellow Ambassador (M) Yellow Monument (R) Yellow Turner (S) Anemone varieties: Dark Pink Norma (M) Enchantress (S) Estrelita (R) Frieda (S) Garza Supreme (S) Little America (R) Long Island Beauty (R) Nevada (S) Norma (M) •Orchid Beauty (R) Shasta (S) The Titan (M) Yolanda (S) Pompon and decorative varieties: Arcadia (R) Avalanche (R) Burgundy (R) Clara Jameson Improved (R) Firebird (R) Gold Coast (M) Golden Feather (Source d'Or) (R) Irene (R) Jewel (R) Lillian Doty (R) Masterpiece (R) Navaho (R) Nuggets (R-) Pink Dot (R) Pinocchio (R) Robin Hood (M) Seafoam (R) Seagull (R) Thyra (R) William Doty (R) Yellow Bushnell (M) Yellow Fellow (R) Yellow Hammer (R) Single varieties: Dark Pink Valencia (S) Ida Skiff (R) October Pink (M) Valencia (S) Hardy varieties: Indian Summer (R) Normandy (R) Virus stunt. This disease is trans- mitted to chrysanthemums by aphids that have fed on diseased plants; and by cultural operations, such as tilling, fer- tilizing, disbudding, and tying, where implements or the grower's hands are contaminated by work on diseased plants. [20 In most commercial varieties the disease takes from 4 to 6 months, and in some varieties 10 months, to become notice- able. Affected flowers bloom too early, on stems much shorter than normal. Color-fading follows — red flowers tend- ing to fade into yellow or dirty white. There is no control of virus stunt ex- cept to start with disease-free rooted cut- tings. At present, disease-free rooted cuttings are available only in the eastern states. In time, guaranteed disease-free cuttings may become available in Cali- fornia so that chrysanthemum fanciers will be in a position to start with healthy stock. Miscellaneous diseases. Other dis- eases occasionally attacking chrysan- themums include bacterial fasciation; rhizoctonia root rot; and stem canker or stem rot. Bacterial fasciation or "cauliflower" condition is caused by Bacterium fas- cians. When found, it is on stems close to the ground in both garden and green- house. The best control is to propagate with disease-free cuttings and to plant in disease-free soil. Rhizoctonia root rot is caused by the fungus Rhizoctonia solani. It severely damages chrysanthemum plants grown in the open by a brown rot that develops at the base of the plant. The fungus is not limited to chrysanthemums; it at- tacks several kinds of ornamental plants and thus provides many sources of in- fection. Control is preventive. Since the fungus may live over in the soil from one year to the next, gardeners should try to plant in disease-free soil. Some gardeners have even replaced soil where rotation was im- possible. Potting with sterile soil should also help. Stem canker or stem rot, caused by the fungus Sclerotinia sclerotiorum, also at- tacks several different kinds of plants. It is one of the soil-borne and wind-borne diseases that is hard to control in most gardens. In the soil-borne phase, the stems near the ground level are attacked. This is in- dicated by a white surface mold that causes the plants to wilt and suddenly die. In the wind-borne phase, the leaves, blossoms, and stems are attacked by spores blown from surrounding weeds or infected plants of many kinds or from small mushrooms formed on the garden soil by the disease. Control is by preventive measures. It consists of planting in disease-free soil, even to replacing infested soil with dis- ease-free soil and to planting in sterilized soil. These precautions, however, do not rule out the possibility of wind-borne infection. Irrigation also is an important factor. Do not keep the soil around the plants too wet; and do not water over- head. Wide spacing between the plants also is important. Remove and burn all diseased clumps. Plant in foreground was affected by stunt dis- ease. Compare its height with that of normal plant in background. [21] USE EITHER COMBINED-SPRAY OR SEPARATE- SPRAY PROGRAM Combined-spray control for various pests and diseases is used by some gar- deners; separate sprays for the different pests and diseases as they actually appear are used by others. This difference in choice depends on the numbers and kinds of pests and diseases present or antici- pated. If only one pest or disease is involved or if the combined spray is not entirely effective, then to use separate sprays may be the best plan. DDT is combined with chlordane and wettable sulfur, and also with summer oils and lindane. Nicotine sulfate is com- bined with DDT, summer oils, and wet- table sulfur, but is not used with lindane. Wettable DDT is used for chewing in- sects, the gall fly or midge, and thrips; Toxaphene for chewing insects, aphids, mites, and thrips; lindane for gall flies or midges, leaf miners, and thrips. Parzate, Fermate, and Dithane D-14 are used for some kinds of leaf spot, powdery mildew, rust, and damping-off. The container for each spray material usually lists combinations permitted and combinations to be avoided. The label should also indicate whether the spray is poisonous. If directions do not appear on the container or cannot otherwise be ob- tained, ask an authority, such as the Farm Advisor or a reputable nurseryman.

[22] CLASSIFICATION OF CHRYSANTHEMUMS Chrysanthemum flowers are classified as to form, size, and color, and sometimes as to season of bloom and resistance to cold (table 2). Some fanciers are interested in training plants into some special form, such as cascade (table 4) or fountain. A few chrysanthemums are flowered in pots for exhibition. Odd forms (table 3) may be of interest. Nurserymen who sell plants have classes such as those listed in the tables, but no widely recognized system of classification for exhibition purposes has yet become official. A few fanciers have been trying to improve the classification, and there is already considerable agreement among them, although the relative order of the classes may differ. The following classification for show purposes is presented with the hope that it will help beginners interested in the different flower types and the names applied. In time an official system of classification that is widely recognized should be adopted. The following descriptions may be used to determine where any particular variety should be placed for exhibition purposes. I. Singles Section (table 1). A. Standard Singles, Should have from 1 to 5 rows of petals and an open center or disk ; petals of moder- ate breadth. 1. Small: not over 2 inches in diam- eter. Examples: Anna, Jane Harte (sport of Anna). 2. Intermediate: over 2 inches but not over 4 inches in diameter. Ex- amples: Mrs. Buckingham, Octo- ber Pink, Red Daisy. 3. Large: over 4 inches. Examples: Gretchen Piper and Valencia, when well grown and disbudded. B. Broad-pet cr/ed Singles. Petals normally very broad, as in some dahlias. Examples: Buttercup, Car- men, Golden Pride, Paloma, Sensa- tion. (Note: Single spoon and match- stick types are listed under Spoon Chrysanthemums. ) II. Semidoubles Section. Flowers with more than 5 rows of ray petals and with disk showing. Some chrysanthemum catalogs list single varieties with several rows of petals (4 or 5 rows) as semidouble, but this term really applies to the more markedly doubled kind that retains an open center. Few varieties fall within this section, so there is little need to make a further segregation as to diameter of Left— intermediate single with two rows of petals; right— intermediate standard single with several rows of petals. A Left— informal single, or daisy type, with one row of petals; right— Pink Exquisite, with its interesting, twisted center. the flowers. Example: The Chief and Melba. Some semidouble varieties may have quilled petals with semispoon tips, as Laurinda Early. III. Anemone Section (table 5). The flowers resemble singles with 1 to 5 rows of ray petals, but the central florets are raised to form a cushion. This cushion may be relatively small as in Frieda and The Titan or it may be broad and high as in Estrelita and Sin- cerity. A. Regular Anemone. Ray petals evenly spaced and of about equal length. 1. Small Regular Anemone: not over 2 inches in diameter. Examples: Gypsy, Izola, Rhapsody, Burning Ember, Little Princess, Lavender Mist. 2. Intermediate Regular Anemone: Left— one form of anemone type with large cushions; right— a group of anemone-type blooms with cushion centers. Left— the small pompon button type is well illustrated by Nuggets; right— an example of inter- mediate pompon type. over 2 inches but under 4 inches in diameter. Examples: Little America, Garza Supreme, Shasta, Smiths Innocence. 3. Large Regular Anemone : 4 inches or more in diameter. Examples: Frieda, Norma, Pink Supreme, White Supreme. B. Irregular Anemone. Ray petals long and irregular in length, usually pointed, may be twisted ; blooms usu- ally over 4 inches in diameter. Ex- amples: Tuxedo (pink), Bronze Tuxedo, Yellow Tuxedo. (Note: Anemone spoon types are listed un- der Spoon Chrysanthemums.) IV. Pompon and Decorative Section (table 6). The flowers in this section are rarely over 4 inches in diameter, and many are much smaller. There is no disk Left— the spider type has petals with hooked tips; right— the matchstick type has tubular petals with small spoon tips. showing when the flowers are fully open. The strap-shaped petals are found in many rows. Any disk flowers present are hidden by these petals. A. Standard Pompons. Blooms range in size from small buttons to more than 2% inches in diameter, but are rarely over 4 inches. The flowers are usually globular in shape or flattened in the small button type. The petals are usually straight. (See table 6.) 1. Small Pompons (includes But- ton) : less than 1% inches in diam- eter. Examples: Baby, Irene, Iso- bel, Jewell, Nuggets, Pinocchio. 2. Intermediate Pompons: at least 1% inches but less than 2% inches in diameter. Examples: Captain Cook, Cassandra, Mrs. Bulkeley. 3. Large Pompons : over 2% inches in diameter. Examples : the several color forms of Doty, Arcadia, Goldsmith. B. Decorative or Reflexed Pom- pons. These resemble the larger standard pompons, except that the petals are reflexed; occasionally, however, some of the central petals may be incurved for a time. Petals usually shorter and narrower than in Decoratives listed below. 1. Small Reflexed Pompons: under 1% inches in diameter. Examples: Bright Eyes, Mary Pickf ord. 2. Intermediate Reflexed Pompons : at least 1% inches but less than 2% inches in diameter. Examples : Clara Jameson, Yellow Dot. 3. Large Reflexed Pompons: over 2% inches in diameter. Example : Navaho. C. Decoratives. Blooms more than 1% and less than 4 inches in diam- eter. Petals somewhat longer and narrower than in the reflexed pom- pons, and may be pointed; either regularly or irregularly reflexed; inner petals sometimes incurved for a time. Many of the hardy garden Commercial spider; petals are usually tubular for part of length; good substance. varieties fall within this class, and may be divided into: (1) Small, (2) Intermediate, and (3) Large. Ex- amples : Avalanche, Lavender Lady, Natoma. V. Spoon and Matchstick Section (table 7). Usually singles with 1 to 5 rows of ray petals, tubular for part of their length and flared out into a spoon at the tip. A few anemone spoon varieties are listed, and these have a crested center. Semidouble and double spoon types are grown occasionally. A. Standard Spoon. Ray petals tubu- lar for about half their length, and tips flared out into a large spoon. Should not have more than 5 rows of ray petals. The disk is conspicu- ous, with short, even florets. 1. Small Standard Spoon: not over 2 inches in diameter. Example: Dr. Carl Norheim (developed by Oakland Park Department) . 2. Intermediate Standard Spoon : more than 2 inches but less than 3 inches in diameter. Examples: Edward T. Foulkes and Com- mander Norman Miller. [26] Left— the incurved commercial type (as shown also on cover); right— an incurved exhibition type. 3. Large Standard Spoon : over 3 inches in diameter. Examples: Scintillation, Freda Leach. B. Mat chstick or Semispoon Type. About the same as the Single Spoon, except that the ray petals are tubular for well over half their length, and the tips are slightly flared into a small spoon. Some growers place this type in with the Single Spoon or Quilled Single, but judges prefer the Single Spoon as listed above when the two are grouped together. Several varieties may be listed as semispoon in form, and some varieties (for instance, Frolic, Jean Squire) may either be listed here or placed in a separate class. Novelties, such as Oriana, are best segregated into odd or novelty varieties. There may be some varia- tion in the form of flowers on the same plant. Examples: Matchsticks, Pink Matchsticks, White Match- . sticks, Robert Bacon, Snow Queen, Yomei. C. Anemone Spoon. Same as Single Spoon, except for cushion center. Examples: Otto Blum, Reverie. VI. Quilled Section (table 8). The flowers should be fully double with no disk showing. The florets are long, straight, tubular, or quilled, and often radiate to make a spherical bloom. The tips of the petals may be slightly spoon- like or curved slightly, but should not be coiled or hooked. May be subdi- vided into Small, Intermediate, and Large. Examples: Albert Witt, Bess Witt, Copper Rocket, Miss Gena Har- wood, Peggy Ann Hoover, Rayonnante. (Note: This group is often listed with the Spider Section, but the tips are not curled as in true spider varieties.) VII. Thread Section. Petals are very slender and threadlike, usually tubular and either straight or slightly curved. The tips of the petals should not be definitely coiled or hooked. Example. Mignonette, White Thread, and Zaza. These are much like a miniature quilled variety, but the petals may be more curled and twisted. VIII. Spider Section (table 8) . The blooms are usually large, fully or partially double, often with tubular [27] Left— a good example of an irregular incurved type; right— a typical reflexed type. Both of these are commercial types. petals, either reflexed or incurved and sometimes twisted. The exhibition vari- eties are usually tubular, and many lack good substance, while the commer- cial varieties may have thick, broad petals of good substance, and are nor- mally fully double; tips definitely coiled or hooked and either open or closed. A. Exhibition Spiders. Includes the many spider varieties with long, slender petals; a great many do not have good substance. A few are semidouble (Jumbo, Pink Fantasy, Sunspot, Wilhelmina) , but most are fully double (Bunbu, Butterfly, Emerald Isle, Lavender Beauty, Punch Bowl, Kay Tashima, and Wai- kiki). The size may be small, inter- mediate, or large. 1. Small Exhibition Spider: small tubes. Example: Silver Drops. 2. Intermediate Exhibition Spider: medium tubes. Examples: Butter- fly, San Marino, Snowy. 3. Large Exhibition Spider: large or giant tubes. Examples: Jumbo, Kay Tashima, Marsha, Oriental, Silver Lace. B. Commercial Spiders, Either flat or tubular petals of good substance and keeping quality, incurved or re- flexed. Example: Mamoru. IX. Feathered or Hairy Section. The flowers are double with quilled petals that are covered with small hairs (ciliated). Formerly this class was known as Ostrich Plume, and today the class is best known by J. C. Taggart and Yellow Taggarts. X. Large Commercial and Exhibition Section. In general the flowers are large, espe- cially in the exhibition varieties. There is no clear distinction, however, be- tween commercial and exhibition vari- eties. Instead, it is better to segregate the varieties acording to the form of the flowers, and then indicate size where size is important. A. Regular Incurved. Petals are broad, overlap regularly and smooth- ly, and cover over the center of the flower, giving each bloom a globular shape. Many of the commercial vari- eties of earlier days were in this group. 1. Small Regular Incurved: blooms not over 5 inches in diameter. Ex- ample: Hilda Bergen. 2. Intermediate Regular Incurved: blooms more than 5 inches but not over 7 inches in diameter. Ex- amples: Anaconda, Lillian Foltz. 3. Large Regular Incurved : blooms over 7 inches in diameter. Ex- amples : Ambassador, Orchid Queen, Sunnyslope Bronze. B. Irregular Incurved. Petals are twisted and irregularly incurved. The blooms are globular in outline. Here belong the Turners, Pocketts, and many other varieties commonly listed under Exhibition. C. Regular Reflexed. Petals evenly spaced and regularly reflexed and overlapping. The blooms are globu- lar in general outline. Sometimes listed under Reflexed Commercial. Examples: Garnet King, Harvard. D. Irregular Reflexed. Petals are broad and twisted and overlapping. The blooms are usually very large, as in Princess Teru. The size helps place these varieties in Large Exhi- bition in some listings : small, up to 7 inches in diameter; large, over 7 inches in diameter. SUGGESTED READING LIST Cumming, Alex, Jr. 1945.
