Polystichum tsussimense, is one of the basal green ferns in the planting, providing texture and structure, as well a perfect example of fractal forms. A reliable fern with glossy, upright, darkly veined fronds and a delicate spine-pointed tip for shadier spots and underplanting. Polystichum tsussimense is evergreen, but old fronds can be cut back in early spring to reveal the newly emerging purple-tinged fronds that transition to green from neat basal rosettes.
