Native to North America, and found throughout the United States and down into Central America.
A perennial grass that forms clumps, with very tall stems and branching flower heads. The stiff stems turn reddish in the fall to straw colored in the winter, when they persist as dried clumps.
Reproduction is by seeds that germinate in the spring, but clumps are able to spread also by short rhizomes.
Mature plants may grow as high as 3 feet or more, with tall, stiff stems in clumps. The stems are slightly flattened and have long, soft hairs at the upper nodes.
Leaves are smooth or slightly hairy, and often with a light caste to the upper surface. They are folded near the base, only about 1/3 of an inch wide, and up to 12 inches long.
Roots are densely fibrous and form short rhizomes. The flower heads form from early to late summer, being produced from the axils of the upper leaves. They have a conspicuous silky-haired appearance and an extremely elongate shape.
