Bouteloua curtipendula (Sideoats grama)
Marcus, Joseph A.
Side-oats grama is a bunchy or sod-forming grass with 2-3 ft. stems in erect, wiry clumps. Purplish, oat-like spikelets uniformly line one side of the stem, bleaching to a tan color in the fall. The basal foliage often turns shades of purple and red in fall. This is a perennial warm season grass; clump forming. Two varieties are recognized: variety curtipendula is shorter and more rhizomatous and ranges from southern Canada to Argentina. Variety caespitosa spreads more by seed than by rhizomes, is more of a bunchgrass, and is restricted mostly to southwestern North America.

Not only is Sideoats Grama the state grass of Texas, but this medium-tall grass mixes well in plantings with spring wildflowers, because it stays short in the spring. Birds love the ripe seeds. In nature, this plant increases rapidly when its site is damaged by drought or grazing.
