Western Wheatgrass has a dense, narrow, 3-6 in. spikes occur at the top of stout culms. The entire plant is often covered with a white coating, lending a silvery caste to its blue-green leaves. The leaves are less than a quarter inch wide and, when dry, roll up longitudinally to display prominent ridges on the tops. Western Wheatgrass is a 15-30 in., cool-season, sod-forming, perennial grass.
This densely colonizing turf grass is commonly found in western North America in low-lying areas subject to seasonal poor drainage. During wet times, this grass becomes aggressive and can crowd out neighboring grasses and forbs. For this reason, and for its silvery blue-green leaves, Western Wheatgrass is favored for erosion control. It covers so thickly, however, that it is not the best choice for a wildflower meadow. It wont allow many other plants room.
