Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Onoclea sensibilis Common Name: Sensitive fern Family: Onocleaceae Author: L. 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: 0.5 Habitat: Wet grassy places, open damp woodland and occasionally on open hillsides[187].
Edible Uses: The young uncurled leaves, often called 'fiddleheads', are used as a vegetable or eaten raw[[159, 177, 183]. Remove the brown scales and then steam the leaves in very little water[213]. The young shoots have been sold as delicacies in Asian markets[213].
Root - cooked[105, 161, 177, 183]. A famine food, it is only used in times of scarcity[213].
