American Mountain Ash
Blue Boy Clematis

American Mountain ash is a beautiful, medium-sized ornamental tree that is ideal for residential lots. Mountain Ash blooms with tiny white flowers in the spring, followed by clusters of small red/orange berries in the summer.

American Mountain Ash's berries stay on the tree throughout the winter. This attracts birds and other small wildlife to your landscape as the berries are an important food source during the winter months.

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.
