Formerly Elymus angustus. Robust, Cool season, long-lived, perennial bunchgrass with short creeping rhizomes. Well adapted to loam and clay soils, drought tolerant and extremely salt and alkaline resistant. Excellent winter hardiness. Root system may extend to 14 ft. below the surface, making it useful for soil stabilization. Excellent forage, especially in winter when plants stand above the snow surface available for grazing. Nearly as productive as Tall wheatgrass (Thinopyrum ponticum) on saline soils.
