原生地・分布（英語）:

説明（英語）: Genus of 42 species of tufted or cushion-forming, subshrubby, evergreen perennials found on shady cliffs in arid mountainous areas of C. Asia. The leaves, usually oblong to spoon-shaped, often with a woolly coating (farina) beneath, are borne in rosettes at the ends of branching shoots. Long-tubed, 5-petalled, salverform flowers, with spreading lobes, are solitary or borne in umbels in spring or early summer. They may be pin- or thrum-eyed and, except for D. involucrata. both variants must be grown together to produce seed. Grow in an alpine house or outdoors in tufa, protected from excess rainfall.

耐寒性（英語）: Fully hardy.

栽培（英語）:

繁殖（英語）: Sow seed in containers in a cold frame as soon as ripe. Take cuttings of single rosettes in summer, and root in a propagating case, watering only from below.

病害虫（英語）: Very susceptible to grey mould (Botrytis), especially if overwatered or poorly ventilated. May be infested with aphids.
