Latin Name:  Blechnum spicant
Common Name:  Hard fern
Family:  Blechnaceae
Author:  (L.)Roth.

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:  0.3   Mature Width:  0.3

Habitat:  Woods, heaths, moors, mountain grassland and on rocks, to 1200 metres[17].

Propagation Notes: Spores - best sown as soon as they are 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. Overwinter for the first year in a greenhouse and plant outside in late spring or early summer. Division in spring or autumn. Larger divisions can be planted straight into their permanent positions whilst smaller clumps are best potted up and kept in a cold frame until they are growing away well.
