Blue Boy Clematis

Arnold Hawthorn is a low-branched tree favored by wildlife and landscapers. This tree's beautiful white flowers and bright red berries make it an attractive ornamental in anyone's yard. Arnold Hawthorn is also used in windbreaks and riparian planting.

Despite its thorns, Arnold Hawthorn is a popular choice of food and shelter for deer and birds. Humans can also eat these berries fresh or preserved, but Arnold Hawthorn will not have high yields until it matures at 5-8 years.

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.
