Bouteloua gracilis


Blue grama


Poaceae (Grass Family)



Bouteloua gracilis (Blue grama)
Crank, Elinor
Only 12-14 in. in full flower, this is among the shortest of the native ornamental grasses. It is fine-leaved and produces blue-green seedheads which are suspended horizontally like tiny brushes from the tip of each stem. The plant turns tan when dormant. Blue grama grows in bunches in the south, and as a sod-former in the north and at high elevations. It is a perennial.

This is an important, drought-resistant, short grass in the mixed prairies and throughout the Great Plains and the Southwest. It can be confused with Hairy Grama Grass (B. hirsuta), which is distinguished by a sharp point extending beyond the florets. A somewhat similar but shorter species, Buffalograss (B. dactyloides), is usually less than 6 inches (15 cm) high and is typical of dry, short-grass plains. Blue grama is commonly planted as a turfgrass mixed with Buffalograss. Great also for planting in a wildflower meadow and grows easily from seed. One of the most important forage grasses in native ranges.

Native Distribution: Western North American from southern Canada to southern Mexico. Western Ontario to Alberta, south through Illinois to western Missouri, Texas, and southern California, through much of Mexico.

Growing Conditions

Water Use: Low , Medium
Light Requirement: Sun
Soil Moisture: Dry
CaCO3 Tolerance: Medium
Drought Tolerance: High
Cold Tolerant: yes
Heat Tolerant: yes
Soil Description: Well-drained, low organic content, gravelly soils or sandy loams, clays. Calcareous or granitic.
Conditions Comments: The most drought-tolerant native turf grass, more so than Buffalograss. Can survive with as little as 7 inches of rain annually. The drier it is, the less likely it will be to form a solid mat by rhizomes; it will stay in separate clumps. For this reason, it is often mixed with Buffalograss and/or wildflowers for a solid cover. The taller you let it grow, the less water it will need, because its roots will be shaded.
