Digitaria cognata is a species of grass known by the common names fall witchgrass, [2] Carolina crabgrass, [3] and mountain hairgrass. [4]
This grass is a perennial without rhizomes. The roots are shallow. The erect stems grow up to 56 centimeters tall. The stem bases are tough and hairy. [2] The leaves are up to 12.6 centimeters long. [5] They are narrow, with "one side wavy, and the other smooth". [3] The inflorescence is a purple-tinged panicle with single-flowered spikelets. [3]
This grass provides graze for livestock and wild ungulates, and birds eat the seeds. [3]
