Blue Lyme Grass

Note: This plant is not currently for sale. This is an archive page preserved for informational use.


Excellent for control of soil erosion on embankments, allow plenty of room for this clumping cool-season grass to sprawl with its underground rhizomes. In late spring, straw-colored seed heads rise 8-12 above the stunning metallic blue foliage.

Leymus Blue Dune makes an excellent, drought-tolerant, taller ground cover. Prefers dry, sunny locations. Cooler autumn weather results in foliage blushed with yellow and rose tones.

Leymus General Information


Leymus is a cool-season ornamental grass, effective for controlling soil erosion. Prefers dry, sunny locations. Allow plenty of room to spread. Blue Lyme Grass will also self-sow, making it a good problem solver for bank stabilization. Not appropriate for a border or specimen planting.

Sorry, we cannot ship Leymus to the counties along the Lake Michigan shoreline in Wisconsin - Door, Kenosha, Kewaunee, Manitowoc, Milwaukee, Ozaukee, Racine, and Sheyboygen." Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Leymus Plant Care

"Does not like a wet site. If needed, cut back after blooming (seedheads) to encourage a flush of bright, fresh autumn growth. Old foliage may be sheared,even to the ground in late fall or early spring."
