Latin Name:  Ophioglossum vulgatum
Common Name:  Adder's tongue
Family:  Ophioglossaceae
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:  0.25   Mature Width:  
 
Habitat:  Damp grassland, fens and scrub[17].



Cultivation Notes:  Prefers a moist free-draining soil[1]. Plants are hardy to about -15°c[200]. The prothalli (a small plant formed when the spore germinates) of this species form a symbiotic relationship with a mycorrhizal fungus in much the same way as orchid seedlings[200]. Members of this genus are rarely if ever troubled by browsing deer[233]. Plants can be hard to establish, they can be naturalized in a meadow or cultivated in the border where they should be left undisturbed[200]. Unlike most species of ferns, the fronds of this species grow up straight and not curled inward, crozier fashion[4].
