Formerly known as Agropyron inermis. Cool season, long-lived perennial, open sod forming drought tolerant grass adapted to a wide variety of sites but intolerant of poor drainage, high water tables and spring flooding. Starts growth early in spring and has relatively short life cycle but renews growth in early fall. Moderately good palatability to livestock and wildlife year-round.
