description_en: Genus of 200-250 species of evergreen, semi-evergreen, and deciduous ferns, many from tropical and subtropical areas of North and South America, but a few from temperate regions of Europe, Asia, Australasia, and North America. Most grow at woodland margins, in shady crevices in rocks, or at stream-sides; some prefer deeper forest shade. The fronds are 1- to 5-pinnate, with oblong or diamond-shaped to rounded segments and usually long, shiny black or deep purple-red stalks; these are produced from often many-branched, long- to short-creeping, sometimes erect rhizomes. Rounded or oblong sori form on the margins of the frond divisions and are covered by kidney-shaped or semi-circular indusia. Adiantums are grown for their elegant foliage and, in many species, the purplish pink colour of the croziers and young fronds. Where temperatures fall below 10°C (50°F), grow tender species in a temperate or warm greenhouse (A. formosum in a cool greenhouse). Grow hardy species, or tender species in warmer regions, in woodland, or in a shady border.

hardiness_en: A. aleuticum, A. capillus-veneris, A. pedatum, and A. venustum are fully hardy or frost hardy. In mild areas, A. formosum will survive short periods of frost if given protection and a sheltered site. The remaining species and cultivars are frost tender.

cultivation_en:

propagation_en: Sow spores as soon as ripe, at minimum 15°C (59°F) for hardy species and 21°C (70°F) for tender ones. Divide rhizomes in early spring. Root plantlets from A. caudatum and others that root at the frond tips. See also p.51.

pests_en: Scale insects may be a problem under glass.
