Blue Boy Clematis
European Hazelnut

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.

European Hazelnut is a large shrub that is native to Europe. It is known for its edible nuts that ripen in late summer to early fall. The nuts can be eaten raw or roasted and have a sweet, earthy flavour. Nut production can start as early as 2-3 years but typically takes until at least 4 years for significant yields.

Catkins appear in late winter to early spring and as they release pollen it attracts bees and other pollinators. Since male and female flowers bloom at different times, multiple shrubs will have to be planted for cross pollination. It is recommended to plant European Hazelnut with other hazelnut varieties such as Beaked Hazelnut, Frank, Yamhill, and York. Planting with other varieties will increase nut production.
