Bluestem is an upright, open to arching perennial with short rhizomes. It naturalizes and spreads to cover an area very quickly. Bluestem usually blooms in August and September and has a light brown to bronze fall color that stays into the winter. It is used as a background plant, in mass planting and in naturalized plantings. Although it performs best in moist, well-drained soil in full sun, its deep root system enables it to survive in hot, dry sites after establishment.
