原生地・分布（英語）:

説明（英語）: Genus of about 10 species of rhizomatous, marshland or marginal aquatic perennials and herbaceous, moisture-loving perennials, widespread in temperate and cold regions of the N. hemisphere. The leaves are generally heart- or kidney-shaped. Those grown as marginal water plants provide a display of cup-shaped, yellow or white flowers in spring. They are borne in terminal or axillary corymbs before the dense clumps of foliage are produced; a second flush of flowers is often produced in late summer. Although calthas are best grown at the water’s edge, several will thrive in a mixed or herbaceous border, if the soil is kept moist. C. introloba is suitable for a peat bed, trough, or alpine house. There is considerable nomenclatural confusion over the limits of the species that are commercially available.

耐寒性（英語）: Fully hardy to frost hardy.
