Carex morrowii, commonly known as Morrow’s sedge, Japanese grass sedge, or kan suge, is a perennial herbaceous plant in the Cyperaceae family. It is native to the understory of cool, moist forests in central and southern Japan, where it thrives in the dappled light and well-drained soils. Morrow’s sedge typically grows to a height of 12-18 inches (30-45 cm) with a similar spread, forming dense clumps of arching, narrow, grass-like leaves. Many cultivars exhibit variegated foliage, adding visual interest to the garden. The plant produces inconspicuous brown flower spikes in late spring, though it is primarily grown for its foliage.

Morrow’s sedge is valued for its ability to tolerate heavy shade and wet conditions, making it an excellent choice for rain gardens, naturalized areas, and as erosion control on slopes. It is also deer-resistant, which is a significant benefit in areas with high deer populations. In cultivation, it requires part shade to full shade, consistent moisture, and well-drained soil to thrive. It is hardy in USDA zones 5 through 9 and adapts well to container growing. While generally low-maintenance, it can be affected by rust and rot if conditions are too wet.CC BY-SA 4.0
