Crimson Passion Cherry
Blue Boy Clematis

Crimson Passion Cherry is a cold-hardy dwarf sour cherry. It produces deep, dark burgundy fruit that are larger and sweeter than other varieties, with a texture that is similar to sweet cherries. They are one of the top varieties for fresh eating but are also well-suited to baking and preserves. In the spring, beautiful white flowers cover the branches, adding ornamental value.

Crimson Passion Cherry was developed at the University of Saskatchewan. It is recommended to grow dwarf sour cherries as a shrub rather than a small tree. The shrub form tends to bear fruit earlier and is less susceptible to winterkill.

Sour cherries are self-fertile; however, planting with additional varieties for cross-pollination can increase yields.

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.
