Autumn Fern is a semi-evergreen to evergreen fern prized for its striking coppery-red to bronze new fronds that mature into a glossy deep green. The young foliage emerges in shades of red, orange, and copper, giving the plant its "autumn" name. The fronds are arching, finely divided, and lance-shaped, creating a lush and textured appearance. The undersides of mature fronds may develop sori (spore-producing structures), adding further interest to the plant.
