Blue Boy Clematis

Canada and American Plum are almost identical in appearance and growth needs. These plants are short and stout fruit trees native to North America.

This hardy ornamental is excellent for both city dwellings as well as rural areas. During the spring, the white and pink blossoms are long lasting. The tasty fruit is suitable for fresh eating, baking, and preserves. These trees are not widely distributed and pure seed can be hard to come by.

Both are commonly used as rootstock and are considered universal pollinizers for other plum varieties.

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.
