I planted two Hyperion Dogwoods (Cornus x ‘KF 111-1’) last fall with one on either side of a path leading at a 45-degree angle into the center garden from the southeast corner. The vision is to have the canopies grow over the path and eventually touch, forming a green “tunnel” during the summer that becomes multi-colored in the fall sporting shades of yellow, purple, and orange. And, perhaps best of all, in spring the trees are smothered in large white bracts.
