Pennsylvania Cinquefoil
Blue Boy Clematis

Pennsylvania Cinquefoil is well suited for naturalisation projects as it is a wildflower native to North America. It is widespread and can be found growing in rocky soils at higher elevations in the mountains and foothills, as well as the dry prairies. The Pennsylvania Cinquefoil is capable of growing in cold, harsh conditions. The bright yellow flowers are found at the top of long stalks in small dense clusters and are ideal for attracting pollinators.

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.
