Japanese Forest Grass is a slow-growing ornamental grass, hardy in USDA zones 5-9, that matures to about 1–1.5 ft × 1–2 ft. It does best in part shade with medium water needs in well-drained and moist soil. Expect yellow and green blooms in summer. It stands up well to black walnut, deer and pollution and grows happily in containers.
