Red Osier Dogwood
Blue Boy Clematis

Red Osier Dogwood is a small deciduous shrub that features deep red stems and twigs year-round, with creamy white flowers in the spring. This shrub will add a nice pop of color to your yard.

Red Osier Dogwood is an excellent soil stabilizer. It is fast growing and becomes drought tolerant once well established.

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.
