description_en: 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.
hardiness_en: Fully hardy.

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