Japanese sedge
Carex kobomugi Ohwi


Japanese sedge is a perennial plant that occurs along coastal areas. Plants, on average, are about 1 ft. (0.3 m) tall. The leaves have small, coarse teeth along the margins of the leaves. Flowering occurs in April to June, with male and female flowers occurring on different plants. Other sedge species that occur in the same habitat flower much later in the year (late summer to fall). Japanese sedge is native to southeastern Asia and was first found in the United States in 1929.
