Adiantum pedatum - L.

Common Name Northern Maidenhair,American Maidenhair Fern
Family Polypodiaceae
USDA hardiness 4-9
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].
Habitats Rich, deciduous woodlands, often on humus-covered talus slopes and moist lime soils, from sea level to 700 metres[270].
Range N. America - Alaska to Quebec and Nova Scotia, south to California and Georgia. E. Asia
