原生地・分布（英語）:

説明（英語）: Genus of about 65 species of creeping, trailing, or tuft-forming, fibrous- or tuberous-rooted, evergreen perennials from woodland, scrub, or disturbed ground in North, Central, and South America. The leaves are alternate, usually fleshy, lance-shaped to ovate, often purple-flushed or variegated, and hairy or hairless. Short-lived, spreading, usually saucer-shaped flowers, each with 3 petals and 3 sepals, are produced in terminal or axillary cymes, which are fused in pairs, with paired, boat-shaped bracts. Hardy tradescantias are suitable for a mixed or herbaceous border. In warm regions, grow the tender species beneath shrubs or for ground cover; in frost-prone areas, grow in a temperate or cool greenhouse, as houseplants, or in a conservatory; they are especially effective in hanging baskets. Contact with the foliage may irritate skin.

耐寒性（英語）: Fully hardy to frost tender.

栽培（英語）:

繁殖（英語）: Insert stem-tip cuttings, 5-8cm (2-3in) long, of the tender tradescantias at any time; root in cutting compost or water, then pot up into soil-based compost (JI No.1). Divide hardy species and cultivars in autumn or spring.

病害虫（英語）: Susceptible to aphids, grubs, and vine weevil.
