Autumn fern (Dryopteris erythrosora, Polypodiaceae) is a slow-spreading semi-evergreen fern from eastern Asia, reaching 1 to 2 feet tall and 2 to 3 feet wide. New fronds emerge in striking coppery-pink tones before maturing to dark green, providing multi-season color interest unusual among ferns.
Autumn fern grows in part shade on moist, well-drained, acidic soils (pH below 6.0) high in organic matter, hardy in Zones 6b to 12b. It is deer-resistant and low-maintenance. No significant pest or disease issues are documented. Cultivars include 'Brilliance' (brighter copper-red new growth) and 'Prolifica' (frond tips produce bulbils).
