Elymus hystrix, Bottle brush grass, grows in a wide range of soil conditions including heavy clay with dry to medium hydrology. Bottle brush grass can take a variety of light conditions from full sun to part shade. It grows 2-3' tall forming fairly loose upright tufts of narrowly bladed green leaves on avg 10" long. The greenish & somewhat bristly flower heads rising well above the foliage in summer resemble bottle brushes. Great perennial competition against Japanese Stiltgrass.
