A shortgrass found mainly on the high plains, it is a valuable fodder. Buffalo grass is co-dominant with Blue grama (Bouteloua gracilis) over most of the shortgrass prairie. Buffalo grass is distributed from central Montana east to Minnesota and south to eastern coastal Louisiana, Texas, New Mexico, eastern Arizona, and northern Mexico. It is incidental in northern Idaho and Virginia. Buffalo grass is a warm-season, native perennial shortgrass. It is drought-, heat-, and cold-resistant. Foliage is usually 2 to 5 inches (5-13 cm) high, though in the southern Great Plains foliage may reach 12 inches (30 cm). Buffalo grass is usually dioecious. Plants are occasionally monoecious, sometimes with perfect flowers. Flowerstalks are 4 to 8 inches (10-20 cm) tall. The male inflorescense is a panicle; the female inflorescense consists of short spikelets borne in burlike clusters, usually with two to four spikelets per bur. Buffalo grass sends out numerous, branching stolons; occasionally it also produces rhizomes. Roots are also numerous and thoroughly occupy the soil. The numerous stolons and roots form a dense sod. Buffalo grass roots are finer than those of most plains grasses, being less than 1 mm in diameter.  www.ake.blogfa.com www.ake.blogfa.com www.ake.blogfa.com
