原生地・分布（英語）:

説明（英語）: Genus of 50 or more species of annuals, biennials, and clump- or mat-forming perennials found in woods, meadows, swampy soils, and at pond margins in Europe, Asia, Australasia, and North and South America. They produce alternate, variably shaped, hairy leaves, and usually paired cymes of 5-lobed, salverform, occasionally funnel-shaped flowers in blue, yellow, or white, mostly with yellow or white eyes. The dwarf perennials are mainly short-lived but self-seed freely; they are useful for a rock garden, bank, scree bed, or alpine house. Grow M. scorpioides at the margins of a pond. M. sylvatica is suitable for a mixed or wildflower border; its cultivars are useful for spring bedding.

耐寒性（英語）: Fully hardy; M. alpestris and M. explanata need gritty, sharply drained soil to survive wet winters.

栽培（英語）:

繁殖（英語）: Sow seed of annuals and biennials in situ in spring or, for spring bedding, in containers in a cold frame or seedbed in early summer. Sow seed of perennials in containers in a cold frame in spring; divide when dormant, and propagate regularly as they are often short-lived. Sow seed of M. scorpioides in situ in mud at pond margins, or in moist compost in containers in a cold frame, in spring; divide and replant in mud or in baskets in shallow water.

病害虫（英語）: Susceptible to powdery and downy mildew. Slugs and snails may cause damage outdoors.
