Woodwardia fimbriata

Woodwardia fimbriata, known by the common name giant chain fern, is a fern species in the family Blechnaceae, in the eupolypods II clade[1] of the order Polypodiales,[2] in the class Polypodiopsida.[3] It is native to western North America from British Columbia through California, including the Sierra Nevada, into Baja California.

It grows in coniferous forests and other moist wooded habitat.[4][5]


Woodwardia fimbriata has very long fronds, each reaching 1 to 3 meters in length.[6] Its sori are short but broad and are arranged in neat lines, the characteristic that gives the chain ferns their name. The chain shape is visible on both sides of each leaflet.


Woodwardia fimbriata is cultivated as an ornamental plant for traditional and native plant gardens, and in natural landscaping and habitat restoration projects. It (or its cultivar(s)) is a recipient of the Royal Horticultural Society's Award of Garden Merit.[7]
