Native to most of the tallgrass prairie region of the U.S., this grass does well in full sun to part shade (although most vigorous in full sun), and in a range of soil types as long as it is not too wet or poorly drained (best in loam to sandy loam though). Very drought tolerant, and does well in areas with hot summers and cold winters (we regularly get periods of -10 to -20 as well as stretches of 90-100).
It is not as tall (@ 2-3') as some of the other tallgrass prairie species, but its unique seed arrangement along the side of the seed stem keeps it from being overshadowed by its bigger co-habitants. IMO, a very attractive grass, & a definite winner in smaller prairie gardens.
Germinates from seed fairly easily, especially in warm soil, with no special pre-treatment necessary.

I love this grass which is native to this part of Texas.. ( Pineywoods, 40 miles north of Houston)
It has seeds that look like oats, all on one side of the stem.
Mine are in some shade and get no supplamental water.They grow to about 2 feet in my yard and go dormant in winter.

Easily grown in average, dry to medium wet soils in full sun. Tolerates wide range of soil conditions from well-drained sandy soils to heavy clays. May be grown from seed and may self-seed in the garden in optimum growing conditions. Cut clumps to the ground in late winter.
