Blue Lyme Grass (Leymus arenarius 'Blue Dune') – 3 Gallon

Description
Blue Lyme Grass, also known as Leymus arenarius 'Blue Dune', is a striking ornamental grass prized for its bold, steel-blue foliage and vigorous, upright habit. This cool-season, semi-evergreen grass forms dense, arching clumps and produces upright, barley-like flower spikes in summer that mature to a light beige. Exceptionally hardy and tolerant of drought, salt, and wind, Blue Lyme Grass is perfect for coastal gardens, erosion control, groundcover, or as a dramatic accent in sunny borders. Its spreading nature makes it ideal for large, open spaces or contained in planters to control its growth. Deer and rabbit resistant, this grass thrives in full sun and a wide range of soils, including sandy and poor soils.
