Woodwardia radicans (L.) Sm.[2] |
Woodwardia radicans, the chain fern,[3] European chain fern or rooting chainfern, is a species of fern in the family Blechnaceae, mainly found in Macaronesia and southwestern Europe, but is also found in southern Italy and Crete. Growing to 1.8 m (6 ft) tall by 2 m (7 ft) broad, it is evergreen with arching fronds. The pinnae have curved, finely-toothed segments. The plant derives its common name from the linked sori on the undersides of the fronds.[4][5]
The specific epithet radicans means "with stems that take root", referring to rooting plantlets appearing at the tips of the fronds.[6]
This plant is cultivated as an ornamental, and in the UK has gained the Royal Horticultural Society's Award of Garden Merit.[7][8] Unlike its hardier cousin Woodwardia unigemmata, it is prone to frost damage and requires protection in colder areas.[9]
