Water Sedge

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.

Water Sedge is a waterside grass which grows an extensive horizontal root system. This prevents erosion and allows it to grow back after being eaten.

Water sedge is grazed by many animals including cattle, sheep, horses and waterfowl. Animals choose Water Sedge for forage later in the year as it stays green longer than other plants, requiring you to buy feed for less of the year.
