Adiantum venustum - D.Don.

Common Name

Evergreen Maidenhair Fern

Family

Polypodiaceae

USDA hardiness

9-11

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

Rock crevices and on forest slopes, 1700 - 2200 metres in Kashmir[145]. Moist, shady, rocky places in Nepal at elevations of 300 - 3,600 metres[272].

Range

E. Asia - Himalayas.

Plant Propagation

Spores - best sown as soon as ripe on the surface of a humus-rich sterilized soil. Keep the compost moist, preferably by putting a plastic bag over the pot. Pot on small clumps of plantlets as soon as they are large enough to handle and keep them humid until they are well established. Do not plant outside until the ferns are at least 2 years old and then only in a very well sheltered position. Division in spring or autumn.
