Dryopteris erythrosora
Also called Japanese Shield Fern
Autumn fern (Dryopteris erythrosora), also called Japanese shield fern, is a semi-evergreen fern with coppery new fronds that mature to dark green. It grows best in cool, shaded spots with moist, humus-rich soil.
Dryopteris erythrosora, the autumn fern or Japanese shield fern, is a species of fern in the family Dryopteridaceae, native to China South-Central, China Southeast, Japan, Korea, Nansei-shoto and Taiwan.
Dryopteris 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 zones 5 to 11. Propagation is by division in spring, separating the small crowns from the larger crowns, or by spores. It is raised as an ornamental plant in gardens because of its color change in the foliage, which change from dark red to dark green, but not very often.
D. erythrosora and the cultivar D. erythrosora 'Brilliance' have gained the Royal Horticultural Society's Award of Garden Merit.
