This is an important native sod-forming grass which occurs over much of the United States. It is especially valuable in the Central and Southern Plains. It grows up to 5 feet tall, with short rhizomes. Leaves are 6 to 18 inches long, 0.25 to 0.5 inch wide. While it grows on most soil types, it thrives best on low, moist areas of good fertility. Growth starts rather late but continues throughout the summer if moisture is available. Yield of forage is high, with quality fair while green; but poor as standing winter feed. Propagation is by seeds.
