Pubescent Wheatgrass is an introduced long-lived sod forming grass.  It has a low tolerance of wet areas and poorly drained soils but is somewhat drought resistant.  Pubescent Wheatgrass is very palatable to livestock producing high quality hay and it is also a very good pasture grass.  As with other aggressive creeping grasses the stand will become unproductive over time as the sod becomes very dense.  For this reason Pubescent Wheatgrass is often included in mixes where erosion control is desired.  Pubescent Wheatgrass is closely related to Intermediate Wheatgrass being similarly adapted.  Intermediate Wheatgrass is shorter lived and not quite as drought tolerant and winter hardy as Pubescent Wheatgrass.
