Autumn Fern, Copper Shield Fern, Japanese Shield Fern
Dryopteris erythrosora — commonly called Autumn Fern — is a semi-evergreen to evergreen fern (perennial) valued for its colorful new growth and year-round presence. It forms a neat, clumping mound of arching fronds that emerge coppery-red to orange in spring, gradually maturing to glossy dark green. The contrast between new and mature fronds provides extended seasonal interest, making it a standout in shaded plantings.
