Is it "Viburnum x Cayuga" or "Viburnum x Carlcephalum"? I know these are two different types and have different characteristics. How can I tell them apart?
These pics were taken April 15, 2012 in the Chicago area. The plant is roughly 7.0-7.5 feet tall (and slightly smaller width). Vase-like shape with even branching inside. As you can see, it has a nice shape and not a lot of holes.
