Dryopteris erythrosa

Dryopteris erythrosora, commonly called Japanese shield fern or autumn fern, is an arching, evergreen fern that grows in a vase-shaped clump to 2′ tall and as wide. It is native to woodland hillsides and mountain slopes in Japan, China and Taiwan. New fronds unfurl in striking shades of orange-red to copper-pink before eventually maturing to glossy deep green by summer. Triangular, bi-pinnate fronds grow to as much as 2′ long. Young sori (spore sacks) are covered by bright red indusia.
