Panicle Hydrangea

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. After the blooms fade, the plant produces silky seed heads that begin as upright, compact tufts and gradually expand into rounded, fluffy clusters, adding texture and interest to the landscape.

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.

Panicle Hydrangea is a large, broad-leaf, deciduous shrub that is prized for its ornamental appeal. It is easy to care for, long-lived, and cold-hardy.

Depending on the variety, its flowers change color throughout the blooming period. Make sure you water Panicle Hydrangeas regularly to achieve the most notable color change.
