If you’re looking for a low-maintenance native grass that can handle tough conditions while adding subtle beauty to your landscape, meet Cusick’s bluegrass (Poa cusickii pallida). This unassuming perennial grass might not win any flashy flower contests, but it’s a workhorse that deserves a spot in native plant gardens across the western United States and Canada.
What Makes Cusick’s Bluegrass Special?
Cusick’s bluegrass is a true native, naturally occurring across an impressive range that spans from the Canadian provinces of Alberta, British Columbia, Manitoba, Saskatchewan, and Yukon, down through the western United States including California, Colorado, Idaho, Montana, Nevada, North Dakota, Oregon, Utah, Washington, and Wyoming. This widespread distribution tells us something important: this grass knows how to adapt and thrive in diverse conditions.
As a member of the grass family (Poaceae), Cusick’s bluegrass brings that classic fine-textured look that works beautifully as a backdrop for showier native wildflowers or as a naturalized ground cover. Its blue-green foliage and delicate seed heads add subtle movement and texture to the landscape without being overwhelming.

Where Does It Fit in Your Garden?
