Blue grama
Blue grama (Bouteloua gracilis) is the defining shortgrass of the western Great Plains, recognizable by its eyebrow-shaped seedheads. It survives on 12 inches of annual precipitation, tolerates heavy grazing, and forms the base of CP2 and CP25 mixes from Colorado and eastern Montana south through the Texas Panhandle.
Why landowners plant blue grama
- Exceptional drought tolerance where tallgrass species fail outright.
- Dense sod-like growth on heavy grazing pressure protects soil from wind erosion.
- High seed count per pound keeps western mixes affordable.
- Excellent forage value cured on the stem into winter.
Site fit
Use across the semi-arid High Plains and on droughty sand or gravel farther east. Blue grama is the standard grass for western CP2 plantings and shortgrass CP25 blends, generally paired with buffalograss, sideoats grama, and western wheatgrass.
Establishment
Small seed sown shallow — 1/4 inch or less — into a firm seedbed. Warm-soil spring or early-summer seeding ahead of monsoon moisture works best in the western Plains.
Management
Grazing tolerant once established. Burn infrequently in dry regions; fire in drought years can damage stands.
CRP practice fit
Core grass in western permanent native grass plantings.
Base of shortgrass and mixed-grass CP25 mixes.
Low-competition grass matrix for dry western pollinator plantings.

Frequently asked questions
Blue grama persists on roughly 10 to 12 inches of annual precipitation, which is why it dominates shortgrass prairie in eastern Colorado, western Kansas, and the Texas Panhandle. Tallgrass species generally need 25 inches or more.
Rarely. In Iowa, Illinois, or Ohio it is outcompeted by taller mesic grasses. Use it only on droughty sand or gravel sites where the mesic species thin out.
