Alpine Bluegrass is a native perennial bunchgrass adapted to cold, high-altitude, and northern environments. It establishes well in harsh mountain and tundra conditions, thriving even in nutrient-poor soils. Its dense tufts provide reliable ground cover in alpine and subalpine habitats.

Hardy and low-maintenance, Alpine Bluegrass is valued in revegetation and erosion control projects due to its strong root system. It provides forage for wildlife and livestock, while its dense growth also offers cover for small animals. Well-suited for reclamation and soil stabilization in high-elevation and northern regions, Alpine Bluegrass is a key species for strengthening fragile landscapes, though it is also found in lower-elevation sites.

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.
