General Information

Blechnum spicant is an evergreen fern, forming a somewhat loose cluster of fronds up to 60cm tall and spreading slowly by short creeping rhizomes. The plant produces two types of frond - sterile fronds are evergreen and spreading, often laying horizontally on the ground by the end of the growing season; whilst fertile fronds are longer and erect, withering by the end of the season[

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[

Cultivation Details

Blechnum spicant has a very wide native range from the Arctic regions of Alaska to the mountains of N. Africa. It grows in hardiness zones ranging from 5 - 8, but avoids areas with low rainfall. Although cold tolerant, young growth in spring can be badly damaged by late frosts.
Best grown in humusy, acidic, evenly moist, well-drained soils in part shade to full shade[

Propagation

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.
