This bright blue, cool-season ornamental grass maintains its coloring throughout the growing season, even in southern gardens. In spring, straw-colored seed heads appear on stalks 8-12 inches above the foliage. Leymus arenarius ‘Blue Dune’ is native to Western Europe where it can be found in sand dunes as well as in rich soil. Blue Lyme Grass spreads by rhizomes, so it can be used as a tall ground cover, on hillsides, and for controlling soil erosion. Blue Lyme Grass prefers dry, sunny locations. Grows 30" tall.
