Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Asplenium scolopendrium Common Name: Hart's tongue fern 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: 0.6 Mature Width: 0.45 Habitat: Moist banks and walls[4], rocks in damp shady places in woodlands[7, 9, 31], often on lime-rich soils[187].
Cultivation Notes: Easily grown in a shady position in a soil that is rich in leaf-mould[187]. Prefers a light sandy soil[1]. Succeeds on chalk[28]. Plants can be grown on drystone walls[219]. Grows well in heavy clay soils. Prefers a shady position with no more than 3 hours sunlight a day, greater exposure will cause yellowing and burning of the leaves[187]. One report says that it succeeds in dry shade[188]. Requires a pH of 6 or more in order to flourish.
Plants are hardy to about -30°c[187], they grow very well in SW. England[31].
A very adaptable plant[28]. There are many named forms, selected for their ornamental value[187, 200].
Members of this genus are rarely if ever troubled by browsing deer[233].
