"Aristida purpurea" is a species of grass native to North America which is known by the common name purple three-awn. This grass is fairly widespread and can be found across the western two thirds of the United States, much of southern Canada and parts of northern Mexico. It is most abundant on the plains. This is a perennial grass, growing erect to under a meter in height, and the flower glumes often assume a light brown to reddish-purple color. There are several varieties with overlapping geographical ranges. This is not considered to be a good graze for livestock because the awns are sharp and the protein content of the grass is low.
