Dryopteris erythrosora (Autumn Fern, Japanese Wood Fern or Japanese Shield Fern) is a species of fern, native to eastern Asia from China and Japan south to the Philippines, growing in light woodland shade on low mountains or hills. It is evergreen, with bipinnate fronds 30-70 cm tall and 15-35 cm broad, with 8-20 pairs of pinnae.


D. erythrosora can tolerate a drier soil than many ferns, but is most successful in moist, humus-rich soil, with a pH range of 6.1 to 7.5, with morning or late afternoon sunshine but not during the middle of the day. It is hardy in zones 5 to 11.

A number of cultivars have been selected, including 'Prolifica' and 'Viridosora'. Propagation is by division in spring, separating the small crowns from the larger crowns, or by spores.
