Aotus. Leguminosæ.

Increased by seeds. In April or September by cuttings of half-ripened wood, inserted in sand under a bell-glass.

Apeiba. Tiliaceæ.

Propagated by well-ripened cuttings planted in sand in heat, under a bell-glass, which should be tilted occasionally to give air.

Aphelandra. Acanthaceæ.

Propagated by cuttings from half-ripened wood taken off with a heel. Cut the base of each clean across; insert an inch apart in pots of sandy soil, and plunge in a brisk bottom heat.

Aphelexis. Compositæ.

Increased by seeds. Also by cuttings made in spring or summer; small half-ripened side shoots are the best; and these will root in sandy soil, under a bell-glass, in a cool greenhouse.

Aphyllanthes. Liliaceæ.

Increased by seeds, which should be sown as soon as ripe in pots in a cool greenhouse. Divisions are also made.

Apios. Leguminosæ.

Propagated by the tubers or divisions of them.

Aplectrum (Putty-Root). Orchideæ.

Increased by the bulb-like subterranean tubers; also by seeds. A difficult plant to grow.

Aplotaxis. See Saussurea.

Apocynum (Dog’s Bane). Apocynaceæ.

Propagated by seeds, suckers and divisions. The best time to divide is just as the plants are starting into growth in spring.

Aponogeton. Naiadaceæ.

Increased rapidly by seeds and offsets. The seeds should be sown as soon as ripe, in pots buried in loam, and covered with glass.

Apple (Pyrus Malus). Rosaceæ.

Standard apple stocks are grown from seeds, and dwarf stocks from layers. Apple seeds are either imported from France or are obtained from pomace. The French seeds give what are technically known as crab stocks, the word crab being used in the sense of a wild or inferior apple. The yearling stocks themselves are imported from France in great numbers. It has been supposed that French crab stocks are hardier and more vigorous than ours, but this opinion is much less common than formerly, and the foreign stocks are not so popular now as the domestic stocks.

The chief source of apple seeds at the present time is the pomace from cider mills. The “cheese” of pomace is broken up, and if the material is dry enough it may be run through a large sieve to remove the coarser parts. The seeds are then removed by washing. Various devices are in use for washing them out. They all proceed upon the fact that the pomace will rise in water and the seeds sink. Some use a tub or common tank, which is tilted a little to allow the water to flow over the side. Others employ boxes some seven or eight feet long, four feet wide and a foot deep, the lower end of which is only eleven inches deep to allow the escape of the water. This box is set upon benches, and a good stream of water is carried into it at the upper end. A bushel or two of pomace is emptied in at a time, and it is broken and stirred with a fork or shovel. When the seeds are liberated they fall to the bottom and the refuse runs over the lower end. Another box is provided with several cleats, at intervals of about a foot, and the ends are left open. The box is set at an angle, and the seeds are caught behind the cleats. Seeds must not stand long in the pomace pile, or they will be seriously injured. Nurserymen like to secure the pomace as soon as it is taken from the press.

As soon as the seeds are collected, they should be spread upon tables or boards, and should be frequently turned until perfectly dry. They may then be stored in boxes in slightly damp sand or sawdust, or in powdered charcoal and kept in a cool and dry place until spring. Or if they are to be sown immediately they need not be dried, but simply mixed with enough dry sand to absorb the water so as to make them easy to handle Seeds should not be allowed to become hard and dry through long exposure to the air, or they will germinate unevenly. Apple seeds procured at the seed stores are often worthless because of this neglect. Very dry seeds can sometimes be grown, however, by subjecting them to repeated soakings and then sprouting in a gentle hot-bed or mild forcing-house. Change the water on the seeds every day, and at the end of a week or ten days mix with sand and place in a thin layer in the hot-bed. Stir frequently to prevent molding. When the seeds begin to sprout, sow them in the open ground. This operation, which is sometimes called pipping, may be performed in a small way by the kitchen stove. Seeds are sometimes “pipped” between moist blankets. (See also page 17.)

When sowing is done in the fall, the seeds may be sown in the pomace. This entails extra labor in sowing, but it saves the labor of washing. This practice gives good results if the pomace is finely broken, and it is now common among nurserymen.

In loose and well-drained soils, sowing is undoubtedly best performed in the fall, just as early as the seeds are ready. But upon land which holds much water, and which heaves with frost or contains much clay, spring sowing is preferable. In spring, the seeds should be sown just as soon as the ground can be worked.

If the stocks are to be cultivated with a horse, the rows should be three or three and a half feet apart. Some growers sow in narrow drills and some in broad ones. The broad drills are usually six to ten inches wide. The earth is removed to the depth of two or three inches, if it is loose and in good condition, the seed is scattered thinly on the surface and the earth hoed back over them. If the ground is likely to bake, the seeds should not be sown so deep; and it is always well, in such cases, to apply some very light and clean mulch. The plants should be well cultivated during the season, and they should attain a height of six to twelve inches or more the first year. If the plants come thickly, they must be thinned out.

In the fall of the first year the seedlings should be large enough to be dug and sold to general nurserymen. Sometimes the poorest plants are allowed to stand another year, but they are usually so scattering that they do not pay for the use of the land, and they should be transplanted the same as the larger stock, or the weakest ones may be thrown away. The stocks are dug with a plow or tree-digger and heeled-in closely, so that the leaves “sweat” and fall off. The plants are then stored in sand, moss or sawdust in a cellar. Before they are shipped the tops are cut off near the crown, usually with a hatchet on a block. The stocks are then graded into budding and grafting sizes. The general nurserymen buy these stocks in fall or early winter. Those which are root-grafted are worked during late winter, but those intended for budding, or which must be grown another season before they attain sufficient size for working, are “dressed” (See Chapter V) and heeled-in; in the spring they are set in nursery rows, from a foot to eighteen inches apart in the row. The nurseryman reckons the age of his tree from the time the seedling is transplanted, rather than from the time the seed was sown.

Seedling raising is usually conducted by men who make it a business and who supply the general nurserymen of the country. It is largely practiced at the west, where the deep and strong soils produce a rapid growth. The yearling trees are graded by the western growers into about four lots: “Extras,” or those at least one-fourth inch in diameter at the crown and having twelve inches of both top and root; these are used mostly as budding stocks the next season, “Commons,” those between three-sixteenths and one-fourth inch at the crown and having eight inches of root; these are used for immediate root-grafting. “Second-class,” those from two to three-sixteenths inch at the crown, and “third-class,” or all those under two-sixteenths. The last two classes must be grown in the field for one or two seasons before they can be worked.

Dwarf stocks are mostly obtained from mound-layering. The common stock for dwarfing is the Paradise apple, a dwarf variety of the common apple species (Pyrus Malus). This variety rarely attains a height of more than four feet. A larger or freer stock is the Doucin, also a variety of Pyrus Malus, which will produce an engrafted tree intermediate in size between that given by the Paradise and free or common stocks. This is little used in this country. To obtain stools for mound-layering, the tree, when well established, is cut off within four or six inches of the ground in spring, and during the summer several shoots or sprouts will arise. The next year the stool is covered by a mound, and by autumn the layers are ready to take off. Sometimes, when stocks are rare, mound-layering is performed during the first summer, before the young shoots have hardened, but good stocks are not obtained by this method. Common green layering is sometimes practiced the first year, but it is not in favor. The dwarf stocks, in common with all apple stocks, may be propagated by root-cuttings and by hard-wood cuttings.

Apple stocks are either grafted or budded. Root-grafting is the most common, especially at the west where long scions are used in order to secure own-rooted trees. (See Chapter V.) Budding is gaining in favor eastward and southward; it is performed during August and early September in the northern states, or it may be begun on strong stocks in July by using buds which have been kept on ice. Stocks should be strong enough to be budded the same year they are transplanted, but the operation is sometimes deferred until the second summer. Stocks which cannot be worked until the second year are unprofitable, especially on valuable land. For root-grafting, strong one-year-old roots are best, but two-year-olds are often used.

In common practice, the root is cut into two or three pieces of two to three inches each, but stronger trees are obtained, at least the first year or two, by using the whole root and grafting upon the crown. The lowest piece is usually small and weak and is generally discarded.

The apple is easily top-grafted and top-budded. (See Chapter V.)

Apple Berry. See Billardiera.

Apricot (Prunus Armeniaca). Rosaceæ.

The apricot thrives upon a variety of stocks. Apricot stocks are used in apricot-growing regions, especially for deep and rich well-drained soils. The pits grow readily if given the same treatment as that detailed for the peach (which see). The stocks are also handled in the same manner as peach-stocks. Apricots upon apricot roots are not largely grown outside of California, in this country. Apricot stocks can be grown from root-cuttings the same as cherries and other stone-fruits.

The apricot does well upon the peach, especially on light soils. In the warmer parts of the country peach is much used.

Plum stocks are commonly used at the north, especially if the trees are to be planted in moist or heavy soils. The common plum is generally used, but some of the native plum stocks are now coming into favor, especially in trying climates. The Russian apricots, which are a hardy race of Prunus Armeniaca, are grown in colder climates than the common varieties, and they therefore demand hardy stocks. Any of the native plums make good stocks, but the Marianna is now coming into especial prominence. The myrobolan plum can be used for all apricots, but it is not popular, particularly in severe climates.

The almond, both hard and soft-shelled, is sometimes used for the apricot, but the union is likely to be imperfect and it is not recommended. Almond-rooted trees are best adapted to light soils.

Varieties of apricots are usually budded, in the same way as the peach, although they may be side-grafted at the crown in the nursery row.

Aquartia. See Solanum.

Aquilegia (Columbine). Ranunculaceæ.

Increased by seeds. They must be sown very thinly, soon after being ripe, in a sandy soil or in pans in a cold-frame. Division of the root is the only way to perpetuate any particular variety with certainty.

Arthrostemma. Melastomaceæ.

Propagated by cuttings of small firm side shoots, which will root, in April or August, under a hand-glass in sandy soil.

Artichoke (Cynara Scolymus). Compositæ.

Usually grown from seeds. Although the plant is perennial, a new stock should be started about every other year. It may be increased also by suckers or divisions of the stools.

Artichoke, Jerusalem (Helianthus tuberosus). Compositæ.

Commonly increased by means of the tubers, which may be planted whole or cut into eyes, after the manner of potatoes. Seeds are very rarely used.

Artocarpus (Bread Fruit). Urticaceæ.

Propagation is difficult. Suckers may be utilized when procurable. The young and slender lateral growths are used for cuttings.

Arum. Aroideæ.

Propagated by seeds, but usually by division of the roots, the best time being just as they begin their new growth, securing as many roots as possible to each division. Any rootless pieces should be placed in heat shortly after removal; this hastens the formation of roots and excites top growth. Arisæmas are treated in the same way.

Arundinaria. Gramineæ.

Increased by division of the root.

Arundo (Reed). Gramineæ.

Propagated by seeds or divisions, spring being the best time for either method. In early autumn, the canes can be cut into lengths of 18 to 24 inches and partly buried in sand in a gentle bottom heat, laying them horizontally.

Asarum. Aristolochiaceæ.

Propagated easily by divisions in spring.

Ascaricida. See Vernonia.

Ascium. See Norantea.

Asclepias (Milkweed, Swallow-wort). Asclepiadeæ.

Increased by seeds sown in pots in spring, pricked out singly when large enough, and treated like cuttings.

Seeds of A. tuberosa must be sown or stratified at once.

Ascyrum. Hypericineæ.

Increased by seeds and by careful divisions of the roots in spring.

Ash. See Fraxinus.

Propagated by young cuttings of half-ripened wood, placed in sand, in spring, under bell-glasses, which must be wiped dry occasionally.

Asparagus. Liliaceæ.

The common kitchen garden asparagus is best propagated by means of seeds. These are sown in spring as soon as the ground can be worked, usually in rows a foot or two apart. Thin the young plants to two or three inches apart in the row and give good culture, and the plants can be set in the field the following spring, and they will give a fair crop after growing there two seasons. Small growers nearly always buy plants of nurserymen. Old asparagus crowns can be divided, but seeds give better plants.

The ornamental species of asparagus are propagated by seeds when they are obtainable; otherwise, by division.

Asperula. Rubiaceæ.

Increased by seeds and by divisions of the roots during spring and early summer.

Asterostigma. See Staurostigma.

Astilbe. Saxifrageæ.

Propagated by division in early spring, and by seeds if they are produced.

Astragalus (Milk Vetch). Leguminosæ.

Seeds should be sown in pots of sandy soil placed in a cold-frame, as soon as ripe, or early in the spring, as they may lie a long time before germinating. The herbaceous perennials also increase by divisions, and the shrubby kinds slowly by means of cuttings placed in a cold-frame.

Astrantia. Umbelliferæ.

Increased by seeds and root divisions in autumn or spring.

Astrapæa. Sterculiaceæ.

Propagated by cuttings of young wood, under a bell-glass in sandy soil.

Athrotaxis. Coniferæ.

Increased by cuttings.

Atragene. Ranunculaceæ.

Seeds should be stratified, and sown in early spring, in gentle heat. By layering in autumn; the layers should not be separated for about a year, when they will be vigorous plants. By cuttings, which should be set in light soil and placed under a hand-glass.

Atropa (Belladonna). Solanaceæ.

Seeds.

Aubletia. See Paliurus.

Aubrietia. Cruciferæ.

Propagated by seeds, which should be sown in spring. In early autumn carefully transplant to a cool shady border. Also by divisions. Where a stock of old plants exists, layer their long slender branches any time after flowering, and cover with a mixture of sand and leaf soil; they will then root freely and establish themselves in time for spring blooming. Cuttings should be “drawn” or grown in a frame until they are soft, before they are removed.

Aucuba. Cornaceæ.

Readily increased by seeds, sown as soon as ripe; or by cuttings, inserted in spring or autumn in sandy soil, with or without a covering.

Audouinia. Bruniaceæ.

Propagated by cuttings of half-ripened wood, in sand, under a bell-glass, in gentle heat.

Aulax. Proteaceæ.

Increased by ripened cuttings, taken off at a joint, and inserted in pots of sandy soil. These will root well under a hand-glass, in a cool house.

Auricula (Primula Auricula). Primulaceæ.

Propagated by seeds, sown as soon as ripe or in spring, in well-drained pots, filled with sandy soil, well watered previous to sowing. Cover lightly with coarse sand, place a pane of glass over the pot, and place the latter in a hand-glass. By offsets, which should be removed when top-dressed, as they are more likely to root. Arrange about four offsets around the sides of well-drained three-inch pots, filled with sandy soil, place under a bell-glass or in a close hand-light, water very sparingly so as to prevent them damping off. After becoming established, admit air, and pot off singly.

Australian Feather-palm. See Ptychosperma.

Australian Mint-bush. See Prostanthera.

Avens. See Geum.

Averrhoa. Geraniaceæ.

Increased in spring by half-ripened cuttings, which will root in sand, under a hand-glass, with bottom heat.

Axillaria. See Polygonatum.

Azalea. Ericaceæ.

Increased by seeds, sown as soon as ripe, or early the following spring, in a large shallow frame containing from two to three inches of peat, over which more peat must be spread by means of a fine sieve; do not cover, but water thoroughly. When the seedlings begin to appear they should have air, shade, and a daily sprinkling of water; transplant in autumn in boxes of peat and coarse sand, water, shade and keep close until growth commences. Grafting is largely practiced to increase the stock of named varieties or choice seedlings, the stock most employed being A. pontica for hardy sorts, and some strong-growing variety of A. Indica, like “Phœnicia,” for tender ones. Layering in spring, enclosing the part buried with moss, is also practiced; but the layer must be left two years before separating. Cuttings of the last year’s wood two or three inches long, taken with a heel, root readily in sand; about the end of summer is the best time. When placed outside they should be covered with a hand-light for about two months, and at the end of that time air should be given freely.

Azara. Bixineæ.

Propagated by cuttings.

Babiana. Irideæ.

Propagated quickly by seeds sown in pans, placed in a gentle heat. These will grow at almost any time. The young plants will require to be carefully transplanted each season until they develop into blooming corms. By offsets grown in boxes or planted out in light rich soil until large enough for flowering.

Babingtonia. Myrtaceæ.

Increased by cuttings of the young sterile shoots, which may be planted in sand under a bell-glass, and kept in a moderate heat until rooted, when they should be placed singly in small pots, in a compost of equal parts loam and peat, with a little sand.

Baccharis (Ploughman’s Spikenard). Compositæ.

Increased by seeds sown in early spring, in pans of rich, sandy soil, and placed in a gentle bottom heat of about 65°. Or the seeds may be sown directly in the garden when the weather becomes warm. Varieties increased by layers in late summer, under glass, or by veneer grafting.

Balsamodendron. Burseraceæ.

Increased by cuttings taken from the ripe young wood, in spring, and placed under a hand-glass, in bottom heat.

Balsam-tree. See Clusia.

Bambusa (Bamboo). Gramineæ.

Propagated by careful division of well-developed plants, in early spring, just as new growth is commencing; establish the divisions in pots. If young shoots are layered, leave only the end exposed.

Banana and Plantain (Musa sapientum, M. paradisiaca and others). Scitamineæ.

Edible bananas rarely produce seeds. The young plants are obtained from suckers, which spring from the main root-stock. These suckers are transplanted when two or three feet high. These plants themselves do not produce so good crops as the suckers which arise from them, and are not transplanted. Two or three suckers are sufficient for a plant at a time; what others arise should be transplanted or destroyed. The suckers should be set deep, as low as two feet for best results. In fifteen or eighteen months the plants will bloom, if they have had good care. The stem bears fruit but once, but new stems arise to take its place.

Baneberry. See Actæa.

Banisteria. Malpighiaceæ.

Propagated by cuttings from ripened wood, which will root freely in sandy soil, under a hand-glass, in stove heat.

Banksia. Proteaceæ.

Seeds are very unsatisfactory. Propagated by well-ripened cuttings taken off at a joint, and placed in pots of sand without shortening any of the leaves, except on the part that is planted in the sand, where they should be taken off quite close. The less depth the better, so long as they stand firm. Place them under hand-glasses in a propagating house, but do not plunge them in heat.

Baphia (Camwood, Barwood). Leguminosæ.

Propagated by cuttings, which should not be deprived of any of their leaves. Place in sand under a hand-glass in heat.

Befaria, Bejaria. Ericaceæ.

Propagated by cuttings of young wood, placed in sandy soil, in gentle heat.

Begonia. Begoniaceæ.

Increased by seeds, well-ripened before they are gathered, and kept very dry until sown. For the successful raising of begonias, it is necessary to sow the seed in pans or pots of well-drained, light, sandy soil, which should be well watered before the seeds are sown. The seeds should not be covered with soil, or they will fail to germinate. Place a pane of glass over the pans, and set in a warm house or frame, where a temperature of about 65° can be maintained, and shade from the sun. As soon as the plants are large enough they should be pricked off into pans of light leaf-mould soil, in which they may remain until large enough to be placed singly in pots. By divisions of the rhizomes. Also increased by cuttings, which strike freely in pots of sand and leaf-mould, and placed on a bottom heat of about 70°. Where large quantities are required, a bed of cocoanut fiber in a stove or propagating-frame may be used, and in this the cuttings may be planted, and remain until well-rooted. Leaf cuttings succeed best when laid on sand or cocoanut fiber, and shaded from bright sunlight. Select old, well-matured leaves, and make an incision with a sharp knife across the principal nerves, on the under side. They should then be placed on the sand or fiber, and held down by means of a few pieces of crock. Under this treatment bulbils will form on the lower ends of the nerves of each section of the leaf, and these, when large enough, may be removed from the bed and potted. Fan-shaped pieces of leaves are often used. Leaf cuttings of begonia are described and figure in Chapter IV. Species like B. diversifolia, etc., may be propagated by the bulblets which form in the axils of the leaves. Tuberous begonias are best propagated by seeds, as described above, but stem-cuttings can be used with fair success, if they are cut just below a joint.

Propagated by suckers which are taken from the base of the plant after flowering, when they have attained a good size. The best method to adopt is as follows: Take the sucker in the hand and gently twist it off the stem; next, trim the base by the removal of a few of the lower leaves, and then insert each sucker separately in a small pot, in sharp soil. A bottom heat of about 80° will greatly facilitate new root growth; failing this, they will root freely in the temperature of a stove, if placed in a shaded position for two or three weeks, after which they will bear increased light and sunshine during the latter part of the day.

Propagated by seeds sown when ripe, in bottom heat, or by cuttings put in sand under a hand-glass, in heat; the latter is the better method.

Blackberry (Rubus villosus and vars.). Rosaceæ.

New varieties are obtained from seeds, which may be sown as soon as they are cleaned from the ripe fruit, or which may be stratified until the next spring. If the soil is in prime condition, fall sowing is preferable.

Varieties are multiplied by suckers and by root-cuttings. The suckers spring up freely about the old plants, especially if the roots are broken by the cultivator; but they have few fibrous roots and are inferior. The best plants are obtained from root-cuttings. Roots from one-fourth to three-eighths inch in diameter are selected for this purpose. The roots are dug in the fall, cut into pieces an inch or two long, and stored until early spring. They may be buried in boxes of sand after the manner of stratified seeds, or stored in a cool cellar; callusing proceeds most rapidly in a cellar. The pieces are planted horizontally an inch or two deep, in loose, rich soil. It is best to put them in a frame and give them slight bottom heat, although they will grow if planted in the open in April or May, but the plants will make much less growth the first season. Some varieties do not strike quickly without bottom heat. When the variety is scarce, shorter and slenderer pieces of root may be used, but these demand bottom heat. The heat in the frames is usually supplied by manure, or the heat of the sun under the glass may be sufficient. In these frames the cuttings can be started in the north late in March, or some six or eight weeks before the plants can be set out-doors without protection. When the weather has become somewhat settled, the plants may be planted out, and by fall they will be two to three feet high.

Cabbage Palm. See Areca.

Cabomba. Nymphæaceæ.

Propagated by root divisions.

Cacalia. See Senecio.

Cacao. See Theobroma.

Cactus. Cacteæ.

Propagation by seeds is not often adopted, as it is a very slow method. The seeds should be sown in very sandy soil, and placed in a semi-shady position until germination commences, when they may be exposed and very carefully watered. Usually propagated by cuttings or offsets, which should be made with a sharp cut, and laid upon a sunny shelf or on dry sand until the wound is healed and roots emitted, when they should be potted in sandy soil. Place with the others, and keep syringed. Grafting is resorted to with weak kinds, which will not grow freely except upon the stock of a stronger species; and by this means, also, such kinds can be kept from the damp soil, which frequently causes decay. The stocks usually employed are those of Cereus tortuosus, C. peruvianus, Pereskia aculeata, etc., according to the species intended for working; they readily unite with each other. If the scion and stock are both slender, cleft-grafting should be adopted; if both are broad it is best to make horizontal sections, placing them together and securing in proper position by tying with matting, but not too tightly, or the surface may be injured.

Increased by seeds.

Calandrinia. Portulacaceæ.

Increased by seeds sown in pots where they are intended to flower, as transplantation, unless performed with more than ordinary care, will check their growth or result in loss.

Calanthe. Orchideæ.

As a rule, the natural annual increase in the number of pseudo-bulbs meets the requirements of most cultivators. Where a quick propagation is desired, it may be performed by dividing the pseudo-bulbs transversely; after allowing the raw surface to callus, the upper part should be set on moist sand, and several buds will form around the base. The bottom portion may be used in the ordinary way. Another plan is to divide the pseudo-bulbs lengthwise into two or more pieces. (See under Orchids.)

Calathea. Scitamineæ.

Increased by division in summer or any time between that and the spring months. When making divisions, see that each crown is well furnished with roots.

Calceolaria (Slipperwort). Scrophularineæ.

Herbaceous kinds increased by seeds sown from June to August on pans of light, sandy soil, which should be soaked with water before sowing. Care must be taken to make the surface of the soil level, and also to sow the seed as evenly as possible. It is better not to cover with soil, but a sheet of glass should be laid over the pan, which must be placed in a shady part of the greenhouse or cold-frame until the young plants show the first leaf. The glass can then be gradually removed. The shrubby kinds, by seeds and by cuttings in August. Place in a cold-frame facing the north, in sandy soil, and when rooted, pot off into 3-inch pots.

Calochortus (Mariposa Lily). Liliaceæ.

Propagated by seeds, offsets, and by the tiny bulblets on the upper portion of the stem. Sow seeds as soon as ripe, or early in the year, thinly in pans, so that the young plants may pass a second season in the seed pots on pans. Place in a cool house or frame, and keep the plants close to the glass during their early stages, as they are very liable to damp off. Early the third season pot off and plant singly, encouraging them to grow freely. The offsets are best removed when the plants are in a dormant state, placed in pots or pans, or planted out in pits or frames until they reach flowering size.

Propagated by half-ripened cuttings, which root freely in a mixture of peat and sand, if placed under a glass, in heat.

Camellia, including Thea (Japanese Rose). Ternstrœmiaceæ.

The single red camellia by either seeds, layers or cuttings. Double and variegated camellias by layers, but cuttings will succeed. Seeds give suitable stocks on which to inarch or graft the rarer kinds. The ripened shoots of the preceding summer should be taken off in August. Two or three of the lower leaves should be removed, and the cuttings planted firmly in the soil with a dibble. The pans containing the cuttings should be kept in a plant or cold-frame, without being covered with glass, but shaded during bright sunshine. In the following spring, such as have struck will begin to push, when they need to be placed in a gentle heat. Inarching or grafting is done in early spring, as soon as growth commences.

Increased by well-ripened cuttings taken off at the joint. They will root in sand under a hand-glass, with bottom heat, in spring; but care should be taken not to deprive them of any of their leaves.

Canna(Indian Shot). Scitamineæ.

Propagated by seeds sown in heat in late winter. The seeds are very hard, and germination will be materially stimulated if they are soaked in tepid water for twenty-four hours. They should be sown thinly in pans (a mixture of sand and leaf-loam is best for them), and a covering of one and one-half or two inches of earth is not excessive. It is a good plan to sow the seed singly in small pots. Also increased by divisions; they form a root-stock, each portion of which, with bud and roots attached, may be converted into an independent plant.

Propagated by cuttings of half-ripened side shoots in sand under a glass, in a cool house in late spring.

Carnation. Caryophylleæ.

By propagating by seed, new and excellent varieties are raised. Sow the seeds in April or May, and in a slight hot-bed or in a greenhouse. Also propagated by layering, which should be done at the end of July or the beginning of August. The shoots selected should be denuded of a few of their leaves at the base of the young wood, and a slit must be made from this point upwards, extending through a joint of the bare stem, so that a tongue is formed.

Increased also by cuttings. It is necessary to have a slight bottom heat, and on it put four or five inches of light soil, covered with clean sand. The cuttings must be long enough to have a tolerably firm base, and they must either be taken with a heel or cut off at a joint, and firmly inserted in the soil. This is the ordinary method. See Fig. 52, b.

Carob, Algaroba, or St. John’s Bread (Ceratonia siliqua). Leguminosæ.

They may be increased by means of seeds. Also by dividing the plant during fall. Young cuttings inserted in sandy soil in a cold-frame grow well.

Cherry (Prunus Avium and P. Cerasus). Rosaceæ.

Cherry stocks are commonly grown from seeds. If the ground is in readiness and is in proper condition, the seeds may be planted in fall, or even as soon as they are ripe. If stored until spring, they must be stratified and kept very cool to prevent germination, and they should be sown at the earliest possible moment. They do not need to be cracked by hand. Care must be taken that cherry pits do not become hard and dry. This precaution is more important with cherries than with peaches and plums. At the close of the first season the seedlings will be a foot or foot and a half high, large enough to transplant into nursery rows after the manner of apples, where they are budded the following season. In warm climates the pits are sometimes cracked as soon as they are gathered, and the “meats” planted immediately. They will then make stocks fit for grafting the following winter, or for transplanting and budding the following summer. Cherry seeds must never be allowed to become so dry that the meat is hard and brittle.

Cherries, in common with other stone fruits, grow readily from root-cuttings, in the same manner as blackberries. They do better if started over a gentle heat.

The Mazzard cherry is the stock upon which cherries are nearly always worked. It is simply a hardy and vigorous variety, with inferior fruit, of the common sweet cherry (Prunus Avium). Seeds of this are readily procured in this country. All varieties of cherries are worked readily upon it. The Mahaleb cherry is used as a stock for nearly all varieties when dwarf trees are desired. This is a distinct species, Prunus Mahaleb. The seeds or stocks are usually imported. This stock is adapted to heavy clay soils, while the Mazzard is not. The Mahaleb is not generally used in this country.

Morello (Prunus Cerasus) stocks will no doubt prove to be valuable in the northwest, where great hardiness is demanded. Seedlings do not sprout or sucker badly, but the natural suckers, which are sometimes used for stocks, are likely to be more troublesome in this respect. If strong-growing tops are worked on Morello stocks, however, there is usually little annoyance from suckering.

It is probable that some of the native American cherries can be used as stocks. The common wild red, pin or bird cherry (Prunus Pennsylvanica) has already been used to some extent. The sweet and sour cherries unite readily with it, and bear very early. It is yet to be determined how long the trees will persist, but there are trees known which are sixteen or eighteen years old, and which are still healthy and vigorous. The dwarf or sand cherry (Prunus pumila), especially the western form of it, gives promise as a dwarf stock.

Cherry stocks are worked both by budding and grafting. Budding is the common method. The stocks should be fit to work the season they are transplanted, or in the second summer from seed. Such as are too small for working then may be allowed to stand until the following year.

In the west, where great hardiness is required, the varieties are crown-grafted upon Mazzard stocks in winter. Yearling stocks are used, and the cions are from six to ten inches long. When planted, only the top bud should be left above ground. The cion strikes roots, and own-rooted trees are obtained.

The ornamental cherries are worked upon the same stocks as the fruit-bearing sorts. Mazzard is commonly used for all species.

Chervil (Chærophyllum bulbosum and Scandix Cerefolium). Umbelliferæ.

Seeds, sown much the same as celery seeds, but the plants are usually allowed to stand where sown. Seed is often sown in autumn.

Chestnut (Castanea sativa and var. Americana, and C. Japonica). Cupuliferæ.

Chestnut stocks are grown from seeds. Difficulty is sometimes experienced in keeping the seeds, as they lose their vitality if dried too hard, and are likely to become mouldy if allowed to remain moist. The surest way is to allow the nuts to become well dried off or “seasoned” in the fall, and then stratify them in a box with three or four times as much sand as chestnuts, and bury the box a foot or two deep in a warm soil until spring. They do not always keep well if stored or stratified in a cellar. Fall planting exposes the nuts to squirrels and mice. American stocks are probably better than European.

The stocks are worked by whip-grafting above ground, the wound being well tied and protected by waxed cloth. Care should be taken to have the stock and cion about the same size, in order to secure a good union. Crown-grafting, root-grafting and budding have not been very successful in this country upon the chestnut. The cions should be cut early, before they begin to swell, and kept dormant until the stock begins to push into leaf. Only vigorous stocks should be grafted. The best results are obtained when the stocks have recovered from transplanting, or when they are from three to five years old. The working of chestnut stocks is far from satisfactory in a commercial way. The union is imperfect in many varieties, and usually no more than half the grafts take well.

Chrysanthemum. Compositæ.

Increased by seeds to obtain new varieties; these should be sown in spring. Division may be made, but this is not often practiced. Usually propagated by cuttings of firm, healthy, short-jointed shoots, about three inches long. They should be made in spring, and placed near the glass of a rather close frame having a temperature of about 45°. No bottom heat should be given. If inserted in pots, only the lower leaf should be removed; if in beds the remaining foliage should also be trimmed to admit air. The soil should be made of equal parts of sand, leaf-mould and loam, spreading a layer of sand over the top. Insert about one-half of the cutting, press the soil firmly, and water. Leaf cuttings have been employed. Inarching and grafting may also be performed.

Chrysobalanus (Coco Plum). Rosaceæ.

Then cut them off, with a small piece of the base branch adhering to the young wood; or the shoots may be cut off with one or several of these young branchlets on them. Cut the old branch through at the base of each young one, and insert the cutting with this heel of the old wood entire. In this country, usually grown from common green cuttings in summer.

Cistus (Rock-Rose). Cistineæ.

Propagated by seeds, by layers or cuttings under frames outside, or inside with a gentle bottom heat; but seedlings always make the best plants. The seeds should be sown early in the spring in pans or boxes in a frame, and lightly covered with sifted sandy mould. Cuttings should be made from three to four inches long. They may be struck in spring or autumn, in sandy peat under glass.

Clematis (Virgin’s Bower). Ranunculaceæ.

Clematis may be increased by seeds. The seed vessels should be gathered before autumn, and stored in some dry, cool place till the following spring, when the seeds they contain may be sown in light, sandy soil, and placed in gentle heat till they germinate. By layers outside, put in at any time. All the varieties of clematis may also be readily increased by cuttings made of the young shoots, which may be cut up to every eye and planted in gentle heat. Also by grafting any of the varieties on portions of clematis roots in winter. Good healthy pieces of root obtained from old plants answer the purpose well. See also Atragene.

Cockscomb. See Celosia.

Cocoanut (Cocos nucifera). Palmæ.

The nuts are buried in nursery rows, and the young trees are transplanted. A more common practice is to remove the buried nuts, when they begin to sprout, to the place in which the tree is to stand. A nut is then placed in a hole some two feet deep, which is gradually filled in as the plant grows. In from six to eight years the tree begins to bear.

Codiæum, Croton. Euphorbiaceæ.

New varieties are produced by seed. Increased by taking off the tops of any strong leading shoots, and making them into cuttings. They may be struck by placing singly in small pots and covering with bell-glasses, in strong, moist heat, where they will soon emit roots, without losing any of the leaves attached at the time they were inserted. Or they may placed in a bed of sand.

Coffea (Coffee-tree). Rubiaceæ.

Propagated by seeds. Also by ripe cuttings, which strike freely in sand under glass, in moist heat; and the young plants so raised produce flowers and fruit more readily than those grown from seed.

Seeds. Propagated by cuttings planted during summer.

Coreopsis, Calliopsis. Compositæ.

The hardy annuals, which are largely grown under the name of calliopsis for summer ornamentation, by seed, which should be sown in March in a gentle heat, or outside later. The perennials are propagated also by divisions of the root in autumn or spring, or during the summer by young cuttings, which will strike freely in a cold-frame.

Coriander (Coriandrum sativum). Umbelliferæ.

Seeds sown in fall or spring.

Corn. See Maize.

Corn Salad (Valerianella, several species). Valerianeæ.

Seeds sown in spring, summer or autumn.

Cornus (Dogwood Osier). Cornaceæ.

Increased by seed, suckers of soft wood, layers or cuttings. The herbaceous species, C. Canadensis and C. Suecica, may be increased by division, as also by seeds. The willow-like cornuses grow from cuttings of ripe wood. Named varieties and some species are budded in many cases, especially all the weak-growing sorts. Cornus Mas, raised from seed, is the favorite stock. Shield-budding in late summer and veneer-grafting are most successful. (See Fig. 44.)

Coronilla. Leguminosæ.

By seeds sown as soon as ripe. The hardy species by division. Cuttings strike freely if placed in cold-frames or a cool house under a hand-glass in spring, and when calloused, introduced to gentle bottom heat.

Correa. Rutaceæ.

Seeds. May be propagated by cuttings very readily. Varieties are usually grafted on C. alba.

Cortusa (Bear’s-ear Sanicle). Primulaceæ.

Increased by seed sown as soon as ripe in a cold-frame; also by carefully dividing the roots.

Coryanthes. See Stanhopea.

Corydalis. Fumarieæ.

Increased by seeds, or by dividing the plants directly after flowering. The bulbous-rooted species by offsets.

Corylus (Hazel; Cob-nut). Cupuliferæ.

Propagated by seeds, suckers, layers or cuttings. Grafting and budding are each practicable, and are adopted when growing tall standards or scarce varieties. The seed of all should be sown as soon as gathered, or stored in sand till the following spring. All superior varieties should be increased by suckers or layers. Stools kept for layering must be allowed to make more growth than those used for suckers. Free growth must be encouraged for a year or more, and, any suitable time in winter, the shoots should be bent to the ground, pegged firmly, and covered to the depth of three inches with earth. They will be well-rooted by the following autumn, and may then be removed and planted out permanently.

Corynostylis, Calyptrion. Violarieæ.

Increased by seeds, or by cuttings of the young wood, placed in sand in bottom heat, under glass.

Cosmos. Compositæ.

Seeds, usually started under glass. The tuberiferous species, like Dahlia, which see.

Costus. Scitamineæ.

Increased by dividing the roots.

Cotoneaster. Rosaceæ.

Propagated readily by seed, which should be sown in spring; by layers or cuttings in autumn, or by grafting on C. vulgaris, the common quince, or the hawthorn.

Cotton (Gossypium). Malvaceæ.

Seeds commonly. Grown as a curiosity under glass; it may be increased by soft cuttings.

Cotyledon (Navelwort). Crassulaceæ.

Increased by seed, offsets, cuttings of the stem, and by leaves. The leaves should be pulled off in autumn, laid on dry sand in pans on a shelf in a propagating or other warm house, and not watered until small plants appear at the ends of the leaves.

Cowslip. See Primula.

Crambe. Cruciferæ.

Increased by seeds, by dividing the roots and by root-cuttings. See Sea-kale.

Cranberry (Vaccinium macrocarpon). Ericaceæ.

The cultivated cranberry is propagated entirely by cuttings. These are made from vigorous young runners, from six to ten inches in length, and they are thrust obliquely into the soil until only an inch or two of the tip projects. Some blunt instrument, as a stick, is commonly used to force them into the sand of cranberry bogs. Planting is done in the spring, and the cuttings are taken just previous to the operation. If cranberry seedlings are desired, the seeds should be sown in flats of peaty earth, which are stored until spring in some protected place, in the manner of stratification boxes. The seeds should be covered lightly, preferably with fine moss. The plants are allowed to grow the first year in the box.

Crassula. Crassulaceæ.

Seeds; also by cuttings, which should be taken off and laid for two or three days in the sun to dry before planting.

Cratægus (Haw, Hawthorn). Rosaceæ.

Propagated by stratified seeds. Some growers spread the haws in shallow piles in the fall, and allow them to decay, so that most of the pulp is removed before they are stratified. Haws often come irregularly, even from stratified seeds. The varieties are grafted, rarely budded, on common stocks.

Cress (Lepidium sativum). Cruciferæ.

Seeds, sown at any time of year. See Water-Cress.

Cress, American. See Barbarea.

Cress, Rock. See Arabis.

Crinum. Amaryllideæ.

Increased by seed, sown singly as soon as ripe in three or four-inch pots, in sandy loam and leaf-mould. Place in a temperature of from 70° to 80°, and keep rather dry until the plants appear, when more moisture should be applied. Also increased by offsets, which should be removed when rather small and potted separately, and grown as recommended for seedlings.

Crithmum. Umbelliferæ.

Propagated by seeds sown as soon as ripe, and by divisions.

Crocosmia. Irideæ.

Propagated by seeds sown in pans in a cold house as soon as possible after maturity. Also by offsets.

Crocus. Irideæ.

Propagated by seed, sown as soon as ripe or early in spring, the choicer strains in pots or boxes, using a light, sandy soil, and afterwards placing them in a cold pit or frame; the more common varieties may be placed in a warm position outside in a seed bed. Sow thinly, so that the plants may grow two years in the seed pan or bed without lifting. By the corms. These may be lifted and replanted, allowing each in its turn to develop new corms below. The following year new corms, or cormels, are also formed by the side of the old corms. These old corms die away annually. Some species increase much more rapidly than others.

Crossandra, Harrachia. Acanthaceæ.

Seeds. Propagated by cuttings, which root freely at almost any time of the year, in bottom heat.

Crotalaria (Rattle-Box). Leguminosæ.

Increased by seeds. The shrubby kinds by young cuttings, which root freely in sand, under glass, in a cool house.

Croton. See Codiæum.

Crowea. Rutaceæ.

Seeds. Usually by green cuttings in a frame.

Crowfoot. See Ranunculus.

Crucianella (Crosswort). Rubiaceæ.

Propagated by seeds, by divisions during spring or autumn, and by cuttings.

Cryptomeria (Japan Cedar). Coniferæ.

Increased by seeds, and by cuttings of growing wood planted in sandy soil, under glass.
