Rocky Mountain Fescue

Knotted Rush is a native perennial wetland plant found growing in marshes, swamps, wet meadows, and along shorelines. It spreads by underground rhizomes to form colonies, which can also help stabilize soils and shorelines.

Its upright, slender stems and small clusters of greenish-brown seed heads add structure to wetland plant communities. Knotted Rush is well-suited to wetland conservation, rain gardens, naturalization, and restoration projects. As a cool-season grower, it grows actively during spring and fall, when temperatures are cooler.

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.
