description_en: Genus of about 50 species of rhizomatous, occasionally stoloniferous perennials from mountainous habitats, streamsides, moist meadows, and woodland in arctic and temperate regions of Europe, Asia, New Zealand, North and South America, and Africa. They have unequally pinnate to pinnatisect, wrinkled leaves, the leaflets with toothed or scalloped margins; the leaves are mainly borne in basal rosettes. The erect, open, 5-petalled, saucer- to bowl-shaped, usually upright but occasionally pendent flowers, in shades of cream, yellow, orange, pink, or red, are solitary or borne in cymes, and bloom from late spring to summer. The stems of G. chiloense hybrids tend to be more branched than those of G. coccineum hybrids. The smaller geums are suitable for growing in a rock garden; the larger can be grown at the front of a border.

hardiness_en: Fully hardy.
