Latin Name:  Botrychium virginianum
Common Name:  Rattlesnake fern
Family:  Ophioglossaceae
Author:  (L.)Sw.

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:  0.4   Mature Width:

Habitat:  Rich moist or dry woods[222].

Propagation Notes: Spores - best surface sown as soon as they are ripe in a greenhouse and do not allow the compost to dry out. Placing the pot in a plastic bag helps to maintain a humid atmosphere which promotes germination and growth. Prick out small clumps into pots when they are large enough to handle and keep moist until established. Grow on in a greenhouse for at least the first winter and plant out in late spring. Division. It is best not to try and disturb this plant[200].
