Polypodium lineare - Thunb.

Common Name
Family Polypodiaceae
USDA hardiness Coming soon
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 Epiphytic on tree trunks and rocks in lowland and low mountains all over Japan[58]. Often found on old brick walls[178].
Range E. Asia - China, Japan, Korea.

Cultivation details

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of this country. The following notes are based on the general needs of the genus. Tolerates short periods of drought and direct sunlight, but it prefers bright filtered light[200]. Plants can be grown on a drystone wall[200]. Members of this genus are rarely if ever troubled by browsing deer[233].

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 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[200].
