Agropyron trichophorum Pubescent wheatgrass is a long-lived, sod-forming, cool-season perennial grass that provides a nutritional pasture and is very palatable to all classes of livestock. It is closely related to intermediate wheatgrass but is distinguishable by the pubescence, or presence of short stiff hairs on the heads and seeds, is more winter hardy, much more drought tolerant, and with its ability to spread via rhizomes is a more vigorous sod. Adapted to wide range of soil, elevation and temperature conditions, it is ideal for low fertility and harsh sites. Needs at least 12 water annually, and accepts summer water if available, but may become unproductive in a few years under irrigation. Useful for hay and pasture and stays green into summer if given adequate moisture. Needs good drainage, dislikes wet conditions. Grows to 3-4. Seed 1-1.5 lbs per 1000 sq ft or 12-16 lbs per acre at .5 depth.
