Broomsedge is a perennial weed frequently found in fields, along roadsides, and in openings to forests and pastures. It can be distinguished from other grasses by the flattened leaf sheaths which have obvious leaf hairs. Leaves with folded vernation arise from a basal crown. Immature plants are bluish-green, however mature leaves turn light brown and appear to be dry. These upright leaves remain standing throughout the year.
