  • Description

  • Notes

Sioux Blue is an eye-catching, warm-season, clumping grass that grows about 5 to 6 feet tall (7 feet in flower) and 3 to 4 feet wide. Medium-wide blades are grey-blue and hold their color until the fall, when they turn a lovely yellow-orange. Plumes emerge July until frost, and are coppery-red. Native across much of North America, Quebec west to Dakotas, south to Arizona, Florida, & Mexico.
Grows best with full sun in most any soil as long as it is well drained. Extremely tolerant of cold. Provides erosion control, great dried flowers, and good for livestock. Needs regular watering until established, but then is drought tolerant. Over-watering can make it floppy. Cut back in late winter before new growth emerges; see Guides.
