Dryopteris erythrosora

Japanese shield fern

Dryopteris erythrosora — commonly called Autumn Fern — is a semi-evergreen fern valued for its striking coppery-red new fronds that emerge in spring, gradually maturing to glossy deep green. New flushes of bronze to copper tones can reappear throughout the growing season, adding multi-season color interest. Its arching, vase-shaped form creates a soft, textured look, and in milder climates the foliage often persists through winter.
