Woodwardia radicans - (L.)Sm.

Common Name Chain Fern, Rooting chainfern
Family Blechnaceae
USDA hardiness 8-11
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].
Habitats Woodland margins, often by streams[260].
Range South-western Europe and the Atlantic Islands.

Medicinal Uses



Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Anodyne;  Anthelmintic;  Astringent.

Other Uses

Basketry.

Plants can be grown as a ground cover when spaced about 1 metre apart each way[208]. The dried fronds and stems have been used in making baskets[257].

Cultivation details

Requires a neutral to acid humus-rich soil[200]. Prefers growing in wet conditions, especially near running water[200]. Grows best in semi-shade[188]. This species is not hardy in the colder areas of the country, once established it tolerates temperatures down to about -5°c[200, 260] and succeeds outdoors in the milder areas[208]. Members of this genus are rarely if ever troubled by browsing deer[233]. A very ornamental plant[1].

Propagation

Spores - best sown as soon as they are ripe, though they can also be sown in the spring. Sow them 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 humid until they are well established. Do not plant outside until the ferns are at least 2 years old and then only in a very well sheltered position. Plants produce a plantlet at the tips of each frond. These can be detached from the parent plant and rooted in humid conditions in a frame or the fronds can be anchored down and the plantlet allowed to root in situ[200]. Division in spring[188].
