Sour Cherry
Blue Boy Clematis

Sour Cherry is cold-hardy and typically grows as a small tree. In late spring, it produces clusters of fragrant white blossoms that mature into bright red, tart fruit. Although the cherries can be eaten fresh, they are most commonly used in baking and preserves.

While not native to North America, Sour Cherry serves as a larval host plant for the Eastern Tiger Swallowtail (Papilio glaucus), a butterfly native to eastern North America.

Sour cherries are self-fertile; however, planting near additional cherry trees for cross-pollination can increase yields.

This Sour Cherry is produced from seed collected from an Evans Cherry and is not clonally reproduced.

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.
