Description

General: Grass Family (Poaceae). It is a native, warm-season, herbaceous, perennial bunch grass that begins its growth in April. The culms are up to 5 feet tall, slender, and erect. The purple sheaths are covered with hair, especially during early plant growth. The upper part of the plant is rounded and the lower part is slightly flattened and keeled. The blade is ⅛ to ¼ inch wide, 10 to 16 inches long, usually hairy, and curly at maturity. The ligule is small and membranous. The inflorescence has three to six pairs of racemes about 2 inches long with a small tuft of hair at the base. The spikelets are long and hairy. The sessile spikelet is ¼ inch long with a twisted and bent awn that is up to 1 inch long. The pedicillate spikelet is absent or rudimentary. The pedicel is flattened, densely white pubescent, and shorter than the sessile spikelet. After the seed disperses, a tuft of silver hair remains, which suggests the common name, paintbrush bluestem.
