"

A beautiful tree, well worth planting if conditions permit. It is long lived and full of character with ascending upper branches, glossy leaves and attractive bark. Fruit attracts wildlife. Beautiful examples of the species can be seen along the waterways at the north end of the Pinery Provincial Park in Ontario, Canada.
