Seeds. They may be sown in the open ground in spring, or in the fall and the young plants wintered in a cold-frame, or in a hot-bed or forcing-house in late winter and spring. Brussels sprouts, broccoli and cauliflower are treated in the same manner.
Cabbage Palm. See [Areca].
Cabomba. Nymphæaceæ.
Propagated by root divisions.
Cacalia. See [Senecio].

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.
