Slough Grass is a hardy grass that will happily grow in any wet soil. It is usually found near water and is common haymaking material or forage.

Slough Grass is also useful for erosion control and land reclamation.

Idaho Fescue is a native perennial bunchgrass recognized for its fine-textured, blue-green foliage. Its dense, tufted growth and deep root system make it drought-tolerant and effective at stabilizing soils, particularly on slopes and open grasslands. Its upright, arching form and dense clumps give it strong ornamental value in both natural and designed landscapes.
This hardy grass provides cover for wildlife and forage for grazing animals, while also supporting soil health and habitat diversity. Idaho Fescue is well-suited for erosion control, ecological restoration, naturalization, xeriscaping, and habitat enhancement projects.
