Carex morrowii, the kan suge, Morrow's sedge, Japanese grass sedge or Japanese sedge (a name it shares with Carex oshimensis), is a species of flowering plant in the family Cyperaceae. It is native to central and southern Japan, and has been introduced to Belgium, Denmark and Austria.
An ornamental sedge with a large number of (mostly variegated) cultivars, it tolerates heavy shade and wet soil, and is erosion and deer-resistant. Consequently it is recommended as a slowly spreading ground cover, for naturalizing, and in rain gardens. It is hardy in USDA zones 5 through 9 and does well in containers.
