Cool season, drought-tolerant perennial bunchgrass. Most adapted to deep, fertile, heavy soils, but will occur on thin well-drained coarse sites. Seedlings are weakly competitive but once established mature stands are strongly competitive. Good palatability to livestock and wildlife. Cool season, drought-tolerant perennial bunchgrass.
