'''''Adiantum''''' ({{pron-en|ˌædiˈæntəm}}),<ref>''Sunset Western Garden Book,'' 1995:606–607</ref> the '''maidenhair ferns''', is a [[genus]] of about 200 species of [[fern]]s in the [[family (biology)|family]] [[Pteridaceae]], though some researchers place it in its own family, Adiantaceae. The genus name comes from [[Ancient Greek|Greek]], meaning "not wetting", referring to the [[frond]]s' ability to shed water without becoming wet.
They are distinctive in appearance, with dark, often black [[Stipe (botany)|stipes]] and [[rachis]]es, and bright green, often delicately-cut [[leaf]] tissue. The [[Sorus|sori]] are borne submarginally, and are covered by reflexed flaps of leaf tissue which resemble indusia. Dimorphism between sterile and fertile fronds is generally subtle.
They generally prefer [[humus]]-rich, moist, well-drained sites, ranging from bottomland [[soil]]s to vertical rock walls. Many species are especially known for growing on rock walls around [[waterfall]]s and water seepage areas.
Many species are grown in the [[Horticulture|horticultural]] trade, including all three of the species mentioned, as well as a number of tropical species, including ''A. raddianum'' and ''[[Adiantum peruvianum|A. peruvianum]]''. Both ''A. pedatum'' and ''A. aleuticum'' are hardy to zone 3, and are by far the most cold-hardy members of the genus. ''A. venustum'' is also cold-hardy to zone 5. ''A. capillus-veneris'' is hardy to zone 7.
