Yellow Mountain Avens
Nodding Onion

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.

Nodding Onion is a native perennial wildflower known for its nodding clusters of flowers that range in color from white to pink to purple. The lightly scented blooms provide pollen and nectar for pollinators, especially bees, which can collect while hanging upside down, a capability most other insects lack.

The narrow, grass-like leaves of the Nodding Onion can be used as a seasoning in cooked dishes, though bulbs and raw leaves should not be eaten in large quantities. All parts of the plant have an onion-like aroma when bruised, which helps deter deer and rabbits. They can self-seed readily, so removing spent blooms helps manage their spread. Tolerant of a range of soils, including alkaline, it is well-suited for a variety of plantings, including pollinator gardens and naturalization projects.
