Blue grama is valued as forage, and for landscaping and erosion control. It is tolerant of grazing. Blue Grama flowers are also used in dried flower arrangements. Blue grama is readily established from seed, but depends more on vegetative reproduction via tillers. Seed production is slow, and depends on soil moisture and temperature. Seeds dispersed by wind only reach a few meters; farther distances are reached with insects, birds, and mammals as dispersal agents. Blue grama is the state grass of Colorado and New Mexico, and is listed as an endangered species in Illinois.
The tiny, mature seed heads are curved, resembling a human eyebrow. It is readily established from seed, but depends more on vegetative reproduction via tillers.
It is most commonly found from Alberta east to Manitoba and south across the Rocky Mountains, Great Plains, and Midwest states to Mexico. Blue grama grows on a wide array of topographic positions, and in a range of well-drained soil types, from clay to sand. It is intolerant of wet sites, acid soils, or shaded sites.
Leaves begin to grow from mid-April through June, depending on location. Flowering generally occurs in the summer (July to September). The fruit ripens and disperses from August to October, depending on location.
