Elymus glaucus (Blue wildrye)

Cool season, tufted, perennial bunchgrass which is highly desirable for use in erosion control seedings. Commonly found thriving in moist meadows, woodlands or forests at mid elevations throughout its range. Shade tolerant. Attractive, blue green foliage adds value to commercial landscaping projects where slope or site stabilization is needed. Short-lived but readily reseeds itself. Varieties listed below.

Days to Germination:


Arlington - Excellent seed vigor and seed yield with higher disease tolerance. Use for quick establishing, long-term cover. (Released 1995)

Elkton - Slightly taller in stem height and more persistent than Arlington; initiates spring regrowth and seed maturity earlier. Excellent forage biomass producer. Use for quick establishing, long-term cover. (Released 1997)

Union Flat - Collected from the Palouse Hills region at an elevation 1,800 ft. Rapid emergence and growth rate. Better seed producer than other cultivars. (Released 2008)
