distribution_en:

description_en: Genus of about 40 species of dense, mat-forming, evergreen succulent perennials, mainly from the mountains of Europe and Asia. They bear rosettes of thick, pointed leaves, often with bristle-fringed margins, and sometimes covered with a web of white hairs. Flat, branching, terminal, panicle-like cymes of star-shaped, white, yellow, red, or purple flowers are borne on upright stems in summer. The rosettes die after flowering, but are replaced by new, offset rosettes, borne on lateral runners. Numerous cultivars of hybrid origin are available. Grow in a rock garden, scree bed, wall crevice, or trough, or in containers in an alpine house.
