How to Identify
A tufted fern which grows to 40 cm high. It continues to grow from year to year and grows on dry land. The rhizome or underground stem is thick and fleshy. It does not have scales or hairs. Both fertile and sterile leaves occur from a common stem which is 2-5 cm long. The sterile leaves are 5-45 cm long and 5-20 cm wide. They are triangular shaped. They are divided up to 5 times. They are bright green and resemble parsley leaves. The fertile stalk is 10-20 cm long and branched 2 or 3 times. The spore bodies occur in rows and crowded on either side. The new frond is not curled when a bud.
How to Grow
Prefers a sandy loam with just a small portion of peat. Requires sharp drainage. Best grown in an open position. Plants can be difficult to establish. The prothalli (small 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. A very ornamental plant, it is said to require greenhouse protection in Britain but might survive outdoors in the mildest areas of the country. Some botanists consider this species to be no more than a part of B. ternatum. Unlike most species of ferns, the fronds of this species grow up straight and not curled inward, crozier fashion. Members of this genus are rarely if ever troubled by browsing deer.
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.
