Ophioglossum vulgatum (common name: adder's tongue)

Propagation: Spores - best sown as soon as they are ripe on the surface of a humus-rich sterilized soil. Keep the compost moist, preferably by putting a plastic bag over the pot. Pot on small clumps of plantlets as soon as they are large enough to handle and keep them in humid conditions until they are well established. Do not plant outside until the ferns are at least 2 years old.

Division of underground rhizomes with care because the roots are brittle[1]

Cultivation: Prefers a moist free-draining soil[2].

Plants are hardy to about -15°c[1].

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[1].

Members of this genus are rarely if ever troubled by browsing deer[3].

Plants can be hard to establish, they can be naturalized in a meadow or cultivated in the border where they should be left undisturbed[1].

Unlike most species of ferns, the fronds of this species grow up straight and not curled inward, crozier fashion[4].

Range: Europe, including Britain, from Iceland south and east to N. Africa, north and west Asia.

Habitat: Damp grassland, fens and scrub[5].

Edibility: Used as a vegetable[6]. No more details are given.

Medicinal: The root and the leaves are antiseptic, detergent, emetic, haemostatic, styptic and vulnerary[4][7][8]. An ointment made from the plant is considered to be a good remedy for wounds and is also used in the treatment of skin ulcers[4][6]. The expressed juice of the leaves is drunk as a treatment for internal bleeding and bruising[4].

Soil: Can grow in light, medium, and heavy soils.

Drainage: Prefers well drained soil.

Seed Ripens: Late Spring-Late Summer

Known Hazards: Although we have found no reports of toxicity for this species, a number of ferns contain carcinogens so some caution is advisable[1].

Many ferns also contain thiaminase, an enzyme that robs the body of its vitamin B complex. In small quantities this e
