An evergreen fern forming a striking rosette of bright green sword-shaped blades with highly sinuate, ruffled wavy margins and an obvious dark purplish-black midrib. Prefers bright filtered light, rather than direct sunlight and sufficient warmth and moisture for moderate humidity. Grow I under glass/ frost free in moist but well drained mixture of equal parts loam, leaf-mould/peat substitute and perlite. Water moderately. Slow growing and long-lived.
