Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Dryopteris fragrans Common Name: Fragrant woodfern Family: Dryopteridaceae Author: (L.)Schott. Known Hazards: Although we have found no reports for this species, a number of ferns contain carcinogens so some caution is advisable[200].
The fresh plant contains 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]. However, there have been reports for other species of ferns suggesting that even cooked fronds can have a long term harmful effect. Some caution is therefore advised. Mature Height: 0.2 Mature Width: Habitat: Rocks and screes in Arctic Finland[50].
Propagation Notes: Spores - can be sown at any time of the year in a greenhouse. Surface sow on a sterilised compost and keep moist, possibly by placing the pot in a plastic bag. Germinates in 1 - 3 months at 20°c. Pot up small clumps of the plants when they are large enough to handle and grow on in a shady part of the greenhouse until large enough to plant out.
Division in spring. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
