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.

Slender Wheatgrass is a native perennial bunchgrass common across North America. It establishes quickly, making it effective for site recovery.
It produces upright seed heads that provide seasonal interest and seed for wildlife, and favoured for browsing by elk and sheep. Its seeds are eaten by birds and small mammals, and it provides cover for wildlife.
Slender Wheatgrass is among the first native grasses used for reclamation in western Canada and the U.S. It does exceptionally well in saline soils.
