The hollow stems of this bunchgrass grow in clumps from many scaly, creeping rhizomes. These large, robust plants have bluish grass blades up to 2 feet long. The ligule is a dense ring or cup of hairs on the upper leaf surface at the collar. The panicles are pyramid shaped with many purplish spikelets. The first glume is three-fourths as long as the spikelet and encircles the base of the second glume. In winter the seed head resembles branches of a weeping willow tree.
Switchgrass is a perennial, warm-season, native – 36 to 72 inches tall.
