Rough Fescue is a native perennial bunchgrass valued for its tall, dense clumps and long-lived growth. Adapted to cold climates and nutrient-poor soils, it is a defining species of northern prairie and montane grasslands. In western Canada and the northern Rocky Mountains, Rough Fescue is considered a keystone species because it shapes plant communities, stabilizes soils, and supports ecosystem resilience.

It is a cool-season grass, growing most actively in spring and fall and slowing during the heat of summer. Rough Fescue is highly regarded as forage for wildlife and livestock, with elk, deer, and other grazing animals favoring it. Taller than many other fescue species, it is well-suited to prairie restoration, erosion control, and naturalization projects where it supports both biodiversity and long-term ecosystem health.

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.
