Noted for its incredibly beautiful blue-gray foliage, Leymus arenarius (Blue Lyme Grass) is a vigorous, semi-evergreen grass that grows in densely tufted, spreading clumps of gracefully arching, broad and flat, steel-blue leaves. In summer, it produces sturdy, upright, narrow, blue-gray flower spikes that turn light beige. Spreading aggressively by rhizomes, this grass needs to be used in very specific situations as it is an aggressive grass. Perfect for erosion control or as a groundcover in a wide sunny area, Blue Lyme Grass makes a good container plant where its invasiveness can be contained.

  • Grows up to 2-3 ft tall (60-90 cm).
  • This grass tolerates a wide range of soils from wet to dry and full sun to partial shade. Tends to be less invasive in dry, clay soils.
  • Salt, drought tolerant and deer or rabbit resistant, this cool season grass provides all year around interest thanks to its evergreen foliage in mild winter areas.
  • Cut back foliage in fall. Divide from mid-spring to early fall
  • Native to northern Europe
