Sioux Blue Indian Grass

Sorghastrum nutans 'Sioux Blue'

This handsome, upright, ornamental grass has bright blue-gray foliage that turns yellow, then burnt orange in fall, with showy, bronze-yellow flower plumes. Use in mass plantings for erosion control or allow to naturalize for a prairie effect. Thrives in lean soils with little care. Blooms are stunning in fresh or dried arrangements.

Once established, reduce frequency; very drought tolerant. May self-seed in optimum growing conditions. Cut to the ground in late winter or early spring before new growth emerges.
