Yellow nutsedge is a perennial from rhizomes and tubers that may reach 2 1/2 feet in height. The stems are erect, unbranched, 3-sided and triangular in cross section. Most plants arise from rhizomes and/or tubers. Leaves are 5 to 8 mm wide and do not have ligules or auricles. They are yellow to green in color with a shiny appearance and a distinct ridge along the midvein. Leaves are also produced in groups of 3 from the base of the plant and taper gradually to a sharp point. Spikelets occur at the ends of the solitary stems in a cluster where the flower stalks arise from a common point. Individual spikelets are yellow to brown in color.
