Blue Grama
Bouteloua gracilis
  
About Blue Grama (Bouteloua gracilis) 25 Nurseries Carry This Plant Blue Grama is a widespread, long-lived, warm season, C4 perennial grass native to North America. It is most commonly found from Alberta east to Manitoba and south across the Rocky Mountains, Great Plains, and Midwest states to Mexico. In California it is found primarily in arid mountains of San Bernardino Counties. Blue grama accounts for most of the net primary productivity in the shortgrass prairie of the central and southern Great Plains. Blue grama grows on a wide array of topographic positions, and in a range of well-drained soil types, from fine to coarse textured. Plant height at maturity ranges from 15-30 centimeters. Roots generally extend 30-46 centimeters from the edge of the plant, and 0.9-1.8 meters deep. Maximum rooting depth is approximately 2 meters. In recent years Blue grama has become a popular garden accent grass due to its green to greyish color and interesting seed heads which resemble small penants. There is a popular cultivar known as 'Blond Ambition'.
