Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Cystopteris bulbifera Common Name: Berry bladder fern Family: Dryopteridaceae Author: (L.)Bern. 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: 0.15 Mature Width: 0.23 Habitat: Shaded ravines, rocky (mainly calcareous) slopes and steep banks[43].
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.
Division in spring.
Bulbils are produced at intervals along the midrib and these can be planted into pots as soon as they are ripe[188, 219].
