Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Adiantum pedatum Common Name: Northern Maidenhair Family: Polypodiaceae Author: L. Known Hazards: Although we have found no reports of toxicity for this species, a number of ferns contain carcinogens so some caution is advisable[200].
Many ferns also contain thiaminase, an enzyme that robs the body of its vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase[172]. Mature Height: 0.45 Mature Width: 0.45 Habitat: Moist woods from lowland to middle altitudes in the mountains of Western N. America[60].
Cultivation Notes: Easily grown in a cool moist shady position[1, 187]. Requires an abundance of moisture in the air and soil[1]. Prefers an alkaline soil[200]. Requires an acid soil according to another report.
A very ornamental plant[1], it does not always succeed outdoors in Britain[1]. It probably prefers to be covered in snow overwinter - could a mulch help[1]?
Members of this genus are rarely if ever troubled by browsing deer[233].
Plants have a slowly-increasing rootstock[233].
