Member of the Poaceae family, Broomsedge bluestem is a perennial grass measuring about 3 feet in height. The stem and blades of the grass begin green, and then change color from purple to brownish-orange as the plant ages. Its seeds are small enough to spread by means of wind dispersion, and have a high germination rate. Broom sedge is native to the southern United States, and is found as far north as the great lakes. It is considered an invasive weed in parts of California and Hawaii.
