原生地・分布（英語）: Cosmopolitan

説明（英語）: Genus of about 500 species of fibrous-rooted, bulbous, rhizomatous, or tuberous annuals and perennials, some of which are very invasive weeds. They occur in open habitats or in woodland, and are widely distributed, with many species from southern Africa and South America. Those grown as ornamentals are valued for their palmate, clover-like foliage (some have leaves that fold at night), and for their funnel- to cup- or bowl-shaped, 5-petalled flowers; these are furled umbrella-like in bud, are borne singly or in cymes, sometimes umbel-like, and usually open only in sunlight, closing in dull weather or at night. Woodland species, such as O. acetosella and O. oregana, are suitable for naturalizing in a shady site. Many of the hardy species from southern Africa and South America, as well as various cultivars, are suitable for a rock garden, raised bed, trough, or alpine house. In frost-prone areas, grow the less hardy species in a temperate or warm greenhouse.

耐寒性（英語）: Fully hardy to frost tender.

栽培（英語）:

繁殖（英語）: Sow seed at 13-18°C (55-64°F) in late winter or early spring. Divide in spring; small sections of rhizomatous species root readily with bottom heat.

病害虫（英語）: Prone to rust. May be damaged by slugs and snails.
