Blue Boy Clematis

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.

Blue Boy Clematis is a cold-hardy, fast growing, woody climbing vine. Hundreds of stunning steel-blue bell shaped flowers adorn the vine throughout the summer that droop and appear to hang in the air. The fibrous stems spread and create a fan-like symmetry shape.

This species will do best with support from a trellis, fence, or even other shrubs or tree stumps.

The Blue Boy Clematis was developed in Manitoba, Canada in 1947 by famous breeder Frank L. Skinner by crossing C. integrifolia x C. viticella, but it didn’t gain popularity until the 1990’s.
