I have the cultivar called 'Blue Dwarf' and it is beautiful and healthy. But I want to warn that snow damage can occur very easily, due to the horizontal habit. I had a large limb break the first winter, partially cleaving the trunk. The wound was easily 4 inches long. When I discovered the wound as the snow melted in the spring, I tied the branch back up tightly with panty hose and put a rock snugly under the branch to support it. Amazingly, it has mostly healed. It bled sap for an entire summer but by the next spring, the ooze had about stopped. The limb itself seems healthy and growing. Since then, I have always covered the tree with a plywood tent for the winter.
