Cyrtomium fortunei Evergreen fern (1 Page of 5) The Cyrtomium fortunei plant species is found in E. Asia - China, Japan, Korea. It is a member of the Dryopteridaceae family. Some home gardeners know the variety as C. falcatum fortunei. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Cyrtomium fortunei Family: Dryopteridaceae Author: J.Sm. 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: 0.5 Mature Width: 0.4 Habitat: Thickets in hills and low mountains all over Japan[58]. In China it is found on the sides of ditches and roadways as well as in rocky crevices where it is damp and shady[147].
Propagation Notes: 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. Germinates in 1 - 3 months at 20°c[164]. 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 or summer[188].
