This species produces 2- to 5-foot-tall mounds of narrow green foliage and bottle brush-like silvery-pink to purple flowers, both of which mature to shades of brown. It is the parent of numerous cultivars with notable flowers that range from purple to gray/black. It and some of its cultivars self-sow plentifully in warm climates. It is marginally hardy in Zone 5.

Little bluestem is a tidy, finely textured clumping grass with a blue-green summer color. Its silvery seed heads rise to a height of nearly 2 feet in late summer and are at their best when backlit in the morning or afternoon sun. In fall, the grass turns a rosy rust color that lasts all winter.

No other grass exhibits quite the refinement of texture as this species. Its bright green foliage resembles delicate filaments that arise in elegant, vase-like clumps and spill outward like a soft fountain. All summer it bears a profusion of feathery panicles, which mature from foamy-green to blonde. It is native to the Americas.
