The light-green, upright flower clusters are this perennial grass’ most interesting feature. They are 2-4 in. wide and 6-8 in. long; the bristle-tipped seeds giving the effect of a bottle brush. Bottle-brush grass grows to 3 ft. tall. Wide, wavy-margined leaves are held horizontally from the stalk.
