Giant Chain Fern From the western coast of the USA, Woodwardia fimbriata is a magnificent fern for mild areas, where it will tolerate up to five degrees or two of frost with a thick, dry mulch for winter protection. It’s a very large, evergreen, clump-forming fern, with huge, upright, fresh green fronds, which contrast beautifully with large-leaved plants, like Rheum, which also like a reliably moist soil. Spectacular reflected in a sheltered pool. Protect from cold, drying winds. Holds the RHS Award of Garden Merit.
