This variety of the Korean rock fern is often given species status, but we'll side with the lumpers on this one. Polystichum tsus-simense v. mayebarae makes a 1' tall x 2' wide deer-resistant clump of very dark, evergreen cutleaf foliage on 15" long arching fronds...about 1/3 larger than typical Polystichum tsus-simense. We have found this quite easy to grow in moist or dry shade.
