The Korean Rock fern is a dainty holly fern, small in stature with glossy green leaves that contrast nicely with black scales and leaf bases. It is often grown as a greenhouse plant to be admired at close quarters yet is perfectly hardy. In habitat Polystichum tsus-simense is found on forest floors and rocky slopes and thus makes a perfect fern for growing in the rocky fern garden or at the front of a shaded border. The name Tsus-sima Holly Fern and specific epithet refers to the Island of Tsus-sima, or Tsushima - part of the Japanese archipelago.
