Rocky Mountain Fescue
Tufted Hairgrass

Rocky Mountain Fescue is a native perennial bunchgrass recognized for its fine-textured clumps and adaptability to harsh environments. It grows well in dry, rocky, and nutrient-poor soils and is highly cold-tolerant, making it well-suited to both prairie and alpine habitats. Its fibrous root system contributes to soil stability and helps reduce erosion on slopes and shallow soils.

Widespread across western and northern North America, Rocky Mountain Fescue is an important component of many prairie and alpine ecosystems. It contributes ground cover and organic matter that support soil function, provides cover for small wildlife, and offers moderate forage for grazing animals. Hardy and versatile, it is used in ecological restoration, naturalization, and habitat enhancement projects, particularly in upland and alpine landscapes.

Tufted Hairgrass is a native perennial bunchgrass that forms dense clumps of dark green foliage. It produces tall, wispy seed heads in late spring and early summer, adding height and texture to the landscape. Its tidy, clump-forming habit and ornamental appeal make it well suited to smaller gardens and yards.

Tufted Hairgrass is a cool-season grass that grows most actively during the cooler parts of the growing season: spring and fall. Its adaptability allows it to establish across a range of sites, while its dense, fibrous root system helps stabilize soil. It is well suited to rangeland and prairie restoration, naturalization, erosion control, and revegetation projects.
