原生地・分布（英語）:

説明（英語）: Genus of 44 species of evergreen, cormous perennials usually found in moist, mountainous or submountainous grassland in Ethiopia, E. and S. tropical Africa, and South Africa. Gladiolus-like corms, produced annually, form chains of old corms on top of one another. Basal tufts of semi-erect to erect, thin, grass-like, mid- to grey-green leaves, to 90cm (36in) long, are overtopped in summer by a succession of pendent, funnel- or bell-shaped flowers, borne in spikes on long, slender, arching stems. Hybrids between D. dracomontanum and D. pulcherrimum are sometimes known as Slieve Donard Hybrids, a name wrongly applied to mixed seedlings. In frost-prone areas, grow half-hardy species in a cool greenhouse. Elsewhere, grow tall species at the back of a border or by a pool or stream, and dwarf species in a rock garden or at the front of a border.

耐寒性（英語）: Frost hardy to half hardy; well-established clumps may tolerate temperatures to -10°C (14°F).

栽培（英語）:

繁殖（英語）: Sow seed in a seedbed or in containers in a cold frame as soon as ripe, or divide in spring.
