distribution_en:

description_en: Genus of approximately 20 species of deciduous or evergreen perennials from W. North America, with fleshy rootstocks, and rosettes or tufts of fleshy leaves that vary greatly in shape. The deciduous species occur in open, stony meadows or grassland, and die down after flowering; evergreens are more commonly found in partial shade among rocks or in crevices. The funnel-shaped to open funnel-shaped flowers, each with 5-9, sometimes up to 19 petals, are produced in shades of pink, magenta, purple, orange, yellow, or white. They are usually borne in cymes or panicles, occasionally singly or in racemes or corymbs, in spring and. summer, often over long periods. Grow in an alpine house or rock garden, or in the crevices of a retaining wall.

hardiness_en: Fully hardy.
