Yellow Mountain Avens
Blue Grama Grass

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.

Blue Grama is a native perennial bunchgrass recognized for its blue-green blades and unique seed heads. They grow along one side of the stem and are often compared to eyelashes, eyebrows, or mosquito larvae, which inspired its common names, Eyelash Grass and Mosquito Grass. As the seed heads begin to dry in the fall, they curl, further enhancing the plant’s distinctive appearance. The seeds provide food for birds, and the grass serves as a host plant for certain species of skipper butterflies.

As a warm-season grass, Blue Grama has a slow start in spring and does not actively grow until soil temperatures rise. Its deep roots help with erosion control, and the grass is drought-tolerant once established, thriving even in poor or alkaline soils. It is well-suited for soil stabilization, naturalization, restoration projects, or as an ornamental accent in gardens and landscapes.
