原生地・分布（英語）:

説明（英語）: Genus of about 150 species of biennials and often woody-based perennials found in sunny, rocky sites, often rock crevices, from the Mediterranean to Turkey. They are grown for their nodding cymes of narrowly tubular to cylindrical-bell-shaped flowers, mainly yellow, pink, red, or white. The simple, alternate leaves are covered in fine hairs, contact with which may irritate skin. Grow in a scree bed, or in a rock or wall crevice; in wet climates, they grow best in an alpine house or cold greenhouse.

耐寒性（英語）: Frost hardy; most will withstand temperatures to -10°C (14°F).

栽培（英語）:

繁殖（英語）: Sow seed in containers in an open frame in autumn. Take softwood or greenwood cuttings of shrubs in late spring or early summer.
