Blue Grama native grass

Scientific name

Bouteloua gracilis (Willd. Ex Kunth.) Lag. Ex Griffiths  

Description

Blue Grama is a native, perennial, warm-season, short grass that seldom grows taller than 12 to 20 inches. Blue Grama reproduces only by seed, and as the seed heads mature, they usually bend into a curve that resembles a human eyelash. It produces a low basal type growth that forms a bunchy sod. Blue Grama is grown throughout the Great Plains, and is found in association with buffalograss in the short grass prairies. It is more drought resistant and tolerates alkali conditions better than Sideoats Grama. Blue Grama produces highly palatable, nutritious forage that retains its feed value into the winter. Blue Grama does not produce an abundance of forage, and should not be grazed closer than 2 to 3 inches during the growing season.

Uses of Blue Grama

Erosion control: Blue grama is an excellent choice for erosion control when used as a component in warm season grasses mixes in the short- grass regions of the country.  Blue grama has been used as a low-maintenance turfgrass as well as surface revegetation following mining operations.

Livestock: In southern areas of the U.S. blue grama is primarily a bunchgrass. Under heavy grazing and in more northern states is can form a sod.
