Buttonbush is a moisture loving shrub that provides year round interest.

It has round, fragrant flowers resembling small buttons or pincushions. The flowers transform into small reddish-brown fruit that persists into winter while the leaves take on shades of red in fall.

Providing essential food to bees, butterflies, and other insects, this shrub is versatile. Try it in your next shrub border.

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.
