Black Lady Fern

Athyrium niponicum (a-THEE-ree-um nip-PO-nih-kum)

Family: Athyriaceae Non-native Herbaceous (1-3 ft)

The Japanese painted fern is a herbaceous perennial in the Spleenwort family (Aspleniaceae). Its origin is East Asia, where it grows in rich woodlands. This plant prefers partial to full shade and moist, rich soil, with high organic content. When grown in light shade, the Japanese painted fern has its best color. Excess sunlight washes out the color. The best cultivars have striking silver, green, purple, or red fronds. It grows about 2 feet high by 2 feet wide and adds growth slowly over time. Plants spread by compact, creeping and branching rhizomes, eventually forming a clump. This easy-to-grow fern produces new fronds late in the spring and is not aggressive. It is a great addition as a front border plant in a shaded area, in a woodland area, near water, or in a shade or rock garden. Insects, Diseases, and Other Plant Problems: No serious problems.
