Korean Rock Fern

A diminutive, very hardy fern, Polystichum tsussimense is a clump-forming, evergreen, perennial fern with a very neat, shuttlecock-like habit, ideal at the front of a shady, well-drained border with small, early spring bulbs. The finely divided, narrowly lance-shaped, upright fronds are deep green with a black stem and silvery-white scales. Cut away damaged fronds in early spring to let the new growth show to advantage. Protect the crown against excessive winter wet. Korean rock fern holds the RHS Award of Garden Merit.
