As far as I can recall, no one has compared the roots of a group of dormant (actually dormant in the northern climate) cultivars versus the roots of evergreen (actually evergreen in the northern climate) cultivars.

Actually most (or perhaps even nearly all) cultivars registered as evergreens survive my northern winters quite normally. Most cultivars registered as evergreens act the same way as dormants in my winter climate - that is, they seem to be dormants in a climate where it is appropriate to be dormant and evergreen in a climate where it is appropriate to be evergreen.
