Yellow Mountain Avens is a native perennial wildflower with bright yellow buttercup-like blooms. The nectar-rich flowers attract a variety of pollinators, including bees and butterflies. By thriving at higher elevations, it helps sustain pollinator populations and provides one of the earliest sources of nectar and pollen in alpine habitats.

As a nitrogen-fixing plant, Yellow Mountain Avens enriches soil fertility and supports the growth of surrounding vegetation. It forms dense, spreading mats of evergreen foliage that act as a groundcover and help stabilize soil. Often among the first species to establish in disturbed alpine sites such as glacial outwash or landslides, it is well-suited for alpine revegetation, erosion control, naturalization, and ecological restoration projects in harsh, rocky environments.

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.
