原生地・分布（英語）:

説明（英語）: Genus of 600 species of tuberous, deciduous or evergreen, monoecious or dioecious, climbing perennials, some of which are succulent, from tropical forest and relatively dry, often arid areas in tropical and subtropical regions, and from woodland and open scrub in temperate areas. In a few species, the tubers are at or above ground level and covered with bosses of corky bark, resembling a caudex. The stems are mostly woody based and often become vine-like, with alternate, occasionally opposite, simple or palmate leaves, and axillary racemes of small, bell-shaped, 6-tepalled flowers. Some species produce bulbils in the leaf axils. Use to clothe a pillar or pergola; D. elephantipes is also suitable for a desert garden. In frost-prone areas, grow tender species in a temperate or warm greenhouse or conservatory.

耐寒性（英語）: Fully hardy to frost tender.

栽培（英語）:

繁殖（英語）: Sow seed at 19-24°C (66-75°F), or plant bulbils in spring. Divide tubers when dormant. Root cuttings of young shoots as they arise from the tuber in spring.
