Blue Boy Clematis
Ussurian Pear (Siberian)

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.

Ussurian Pear is the most cold hardy of all pear species. It is frequently used as a rootstock or as a pollinizer for other pear varieties. The pinkish-white flowers that bloom in the spring and the striking fall colours make it well-suited as an ornamental addition to your landscape.

Ussurian Pear can also be used for forming hedges as it tends to branch quite low.

While the Ussurian Pear is considered self-pollinating, planting with another pear variety will increase yields. Can be paired with Krazulya Pear or Beedle Pear.
