Blue Boy Clematis

Showy Mountain Ash is a hardy accent tree. It features pretty clusters of white flowers in spring followed by bright scarlet berries lasting into winter.

Great for small landscapes, Showy Mountain Ash is adaptable to both dry and moist locations, and it is suitable for average home landscape conditions.

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.
