Of cordylines or dracaenas, propagation is usually effected by cutting the ripened stems or trunks, from which all leaves have been removed, into pieces from 2 to 4 inches long. These are laid either in very light soil or in sand in the propagating-bed, where they receive a bottom heat of about 80°, being barely covered with sand or moss (Fig. 1052). The eyes soon start into growth, and, as soon as they have developed about six leaves, these shoots are cut off with a small heel and again placed in the propagating-bed until rooted, after which they are potted off into small pots in light soil, kept close until they become established. They are then shifted on into larger pots as soon as well rooted. They delight in a mixture of three parts good turfy loam and one part well-decayed cow-manure, with a liberal sprinkling of sharp sand. A warm, moist atmosphere suits them best while growing, but towards fall the finished plants must be gradually exposed to full sunshine and a dry atmosphere, which develops their high colors. The kinds enumerated below are such as are mainly grown in large quantities for decorative purposes, and are sold principally during the winter months, especially during the holiday season, when plants with bright-colored foliage are always in strong demand: C. amabilis.—A strong-growing form with broad green foliage, which is prettily variegated with white and deep rose. One of the hardiest varieties, either for decorations in winter or for outdoor work, vases, and the like in summer. D.fragrans,—An African species with broad, massive, deep green foliage which makes noble decorative plants, being frequently grown into specimens from 6 to 8 feet high. Its foliage is of heavy texture, making it a useful plant for the dry atmosphere of a living-room. Two handsomely variegated forms of the above are D. Lindenii and D. Massangeana, both very desirable varieties. C. terminalis.— This is the most popular species, and is grown in immense quantities. The foliage on well-matured plants is of an intense rich crimson marked with lighter shadings. C. australis (commonly called C. indivisa).— Used principally as an outdoor decorative plant in summer, being extensively used for furnishing vases, window-boxes, and the like. It succeeds best when planted out in the open border during summer, potted in the fall and stored during winter in a cool greenhouse. It is propagated almost exclusively from seed, which germinates freely if sown during the early spring months in sandy soil, in a temperature of 60° to 65°, growing them on during the first season in small pots. These, if planted in the open border the second season, fine plants for 6- or 7-inch pots. There are a number of varieties of C. australis, among them several handsomely variegated bronze-colored forms, which, however, are but little distributed yet. Among the principal varieties and species besides the above which are grown in a commercial way are: Baptistii, Shepherdii, stricta grandis, Youngii, Goldieana, Lord Wolseley, De- Smetiana, Sanderiana, Godseffiana, and Mandaeana.

Cordyline is a genus of about 15 species of woody monocotyledonous flowering plants classified in Asparagaceae or alternatively the segregate family Laxmanniaceae, in the Angiosperm Phylogeny Group system, but placed by other authors in Agavaceae or Lomandraceae.
