Botrychium ternatum

Propagation: 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[1].

Cultivation: Prefers a sandy loam with just a small portion of peat[2]. Requires sharp drainage[2]. Best grown in an open position[2]. Plants can be difficult to establish. The prothalli (young plants formed when the spores germinate) of this plant form a symbiotic relationship with a mycorrhizal fungus, similar to the association of orchid seedlings with an invading fungus[1].

A very ornamental plant, it is said to require greenhouse protection in Britain[2] but might survive outdoors in the mildest areas of the country.

Unlike most species of ferns, the fronds of this species grow up straight and not curled inward, crozier fashion[3].

Members of this genus are rarely if ever troubled by browsing deer[4].

Range: E. Asia - China, Japan. N. America.

Habitat: Thickets and grassy places in lowland and low mountains, C. and S. Japan[5].

Edibility: Leaves - cooked[6]. A soft delicious taste[7].

Medicinal: The plant is stomachic, tonic and vulnerary[8][9].

The root is used in the treatment of dysentery[9].

Soil: Can grow in light and medium soils.

Drainage: Prefers well drained soil.

In Leaf: Evergreen

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
