Cystopteris fragilis is a species of perennial fern known by the common names brittle bladder-fern[1] and common fragile fern. It can be found worldwide, generally in shady, moist areas.
Description
It has a short, black rootstock. The leaves are up to 5-25 cm and are borne on fleshy
bitter almond, which is caused spores that contain hydrogen cyanide.[2]
Habitat
The plant, native to for example Finland, grows in places fit for its brittle structure: usually shady and slightly moist areas, in the cracks and ledges of vertical rock faces, blockfields and sometimes on even cliff surfaces as well. It avoids the more most acidic and barren cliffs and prefers especially slightly lime rich soil.[2]
