Polystichum tsussimense

Korean Rock Fern is a versatile, well-behaved little evergreen species. It forms a low mound of dark green fronds with black stems and delicate dark veining through the leaflets. New leaves have a purplish cast. In cold regions this may be grown in a container and wintered indoors. Excellent for edging in the woodland, or in the shady rock garden. Clumps may be divided after 4 to 5 years, in early spring. Trim off any tired looking fronds in spring, and they will soon be replaced by new ones. Tolerates summer heat and humidity.
