description_en: Genus of about 400 species of annuals, biennials, and mainly deciduous, some-times evergreen perennials, widely distributed in temperate regions of the world. They are found in a range of habitats, varying from damp woodland to grassland, and from mountain screes and summer-dry sites to bogs or shallow water. They may be rhizomatous, tuberous, fibrous-rooted, or spread by runners. The leaves form basal rosettes or are sometimes stem-clasping; they are very variable in shape, and may be simple and entire, toothed to palmately lobed, or pinnatisect. Buttercups are grown for their bowl-shaped, or cup-to saucer-shaped, usually 5-petalled, mainly yellow, but also white, pink, orange, or red flowers, which are borne singly or in cyme-like panicles in spring, summer, or occasionally in autumn. Buttercups are suitable for a wide range of sites (see cultivation groups below). Contact with the sap may irritate skin.

hardiness_en: Most are fully hardy. R. asiaticus is half hardy.

cultivation_en:

propagation_en: Sow seed of most alpine species in pans in an open frame when seed is still slightly green; germination is erratic, and pans should be retained for several years if seeds fail to germinate in the first year. Sow seed of perennials, aquatic perennials, and mat-forming alpines in containers in a cold frame as soon as ripe, or divide in spring or autumn. Divide tuberous species, or detach basal bulbils (where these form), in spring or autumn.

pests_en: Vulnerable to slug and snail damage, aphids, and powdery mildew.
