原生地・分布（英語）:

説明（英語）: 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.

耐寒性（英語）: Fully hardy.

栽培（英語）:

繁殖（英語）: Sow seed in containers in a cold frame in autumn, or remove offsets (evergreen species only) in early summer. Seed of L. cotyledon Hybrids does not come true to colour, and many species hybridize freely in cultivation.

病害虫（英語）: Susceptible to aphids under glass, and to slugs and snails outdoors. Prone to neck rot in wet conditions.
