This elegant genus of Palm-like plants, though none are hardy, deserves mentioning here as the species are now extensively employed in Summer decorative gardening. They are erect usually unbranched trees, bearing a tuft of long narrow drooping leaves at the summit of the trunk, which in some species attains a height of 30 or 40 feet. Flowers white, small, in branched panicles, and rarely produced on young plants such as are usually seen in gardens. Fruit baccate, few-seeded. Name from a club. The hardiest species are those from New Zealand, of which C. australis with narrow leaves, and C. indivisa with broad leaves, are the commonest. There are numerous other species in cultivation, frequently under the name Dracaena.
