Leymus Condesatus

Giant Wildrye or Syn

Leymus condensatus (Giant Wild Rye) is a bold, clump-forming ornamental grass with a coarse, upright to arching habit, featuring broad, blue-green to gray-green foliage that creates strong texture in the landscape. Tall flower spikes rise above the foliage in late spring to early summer, adding vertical interest. This species is valued for its drought tolerance, architectural presence, and ability to thrive in tough conditions.
