Heat-loving annual grass weed forming tufts, germinating in late spring. Prefers nutrient-rich, loamy sand to loamy soils.
Youngest leaf is rolled, ovate-pointed, ligules are replaced by a ciliate (eyelash) membrane. The leaf sheath is flattened, glabrous (hairless) and smooth, without auricles. The pseudo-spikes have little spikelets and long, yellow bristles that later turn red, which have no barbs. Approx. 400-500 seeds per plant.
