Blue grama is a low, drought-tolerant perennial grass native to North America, valued for forage, rangeland and erosion control. Its key to growing it is full sun and very well-drained soil, with little water once established.

About
Bouteloua gracilis, the blue grama, is a long-lived, warm-season (C4) perennial grass, native to North America.
It is most commonly found from Alberta, Canada, east to Manitoba and south across the Rocky Mountains, Great Plains, and U.S. Midwest states, onto the northern Mexican Plateau in Mexico.
How to grow it
Blue grama is valued as forage, and is the most valuable grama. It is an ideal range grass in the southwest. It will survive heavy grazing and extreme drought, and is quite palatable to livestock. Grazing of blue grama rangelands might also prevent invasion of undesirable weedy plants.
Blue grama is grown by the horticulture industry, and used in perennial gardens, naturalistic and native plant landscaping, habitat restoration projects, and residential, civic, and highway erosion control. Blue grama flowers are also used in dried flower arrangements. Blue grama is the state grass of Colorado and New Mexico. It is listed as an endangered species in Illinois.
Where it grows
Blue grama has the widest distribution of all grama grasses. It will grow on most soil types, and readily adapts to local conditions. It can be found as far north as Alberta, and as far south as Mexico. It is present in most of the Midwestern United States, extending east to Missouri and Texas, and as far west as Southern California. It has been introduced to some eastern states, as well as South America.
