原生地・分布（英語）:

説明（英語）: Genus of about 150 species of annuals and short-lived, tufted to clump-forming, evergreen perennials, a few of which are succulent. They occur in hot, dry, open, rocky areas, and sometimes grassy or bare alpine steppe or scree, in W. North America, Central America to N.W. and W. South America, and also S. Australia. Although they often appear rosetted, the narrow, entire, usually fleshy leaves are alternate. The 5- to 7-petalled flowers, with 2 large sepals, are usually red, reddish purple, or white, and may be solitary or borne in semi-erect or pendent racemes or panicles on long stalks. In frost-prone areas, treat calandrinias as half-hardy annuals, or grow in a cool greenhouse. Elsewhere, grow on a sunny bank, or in a border, rock garden, scree bed, or alpine house.

耐寒性（英語）: Frost hardy (but intolerant of winter wet) to frost tender.

栽培（英語）:

繁殖（英語）: Sow seed at 16-18°C (61-64°F) in early spring or autumn, or take stem cuttings in spring. Propagate regularly.

病害虫（英語）: Prone to aphids and red spider mites under glass. Young plants are vulnerable to slugs and snails.
