A course, tufted short-lived perennial herb which is 6-24" tall (occasionally taller in robust plants). The stems are smooth and sharply triangular. The leaves are basal, numerous, linear 0.1-0.4" wide and equal in length to the stems. The flowers are several and stalked cylindric spikes arranged in a terminal umbel. Each spike is composed of 5-15 straw-colored flowering spikelets to 1" long. Bloom time July-October. Found in open, wet places and shorelines. The genus name Cyperus is the Greek word for "sedge" and strigosus means "with stiff bristels". The plants in this are sometimes referred to as umbrella sedges. To help tell the difference between rushes, grasses, and sedges, remember the rhyme about the stems, "Rushes are round. Sedges have edges. Grasses have nodes".
