Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Cystopteris montana - (Lam.)Desv.

Common Name Mountain Bladder Fern
Family Dryopteridaceae
USDA hardiness 4-8
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].
Habitats Damp, usually basic, rocks on mountains, 700 - 1100 metres in Northern England and Scotland[17].
Range Northern, but not arctic, Europe, including Britain, east to Siberia. Also in northern N. America.
