Great start, everyone!
Sue, thanks for the additional information. I should have mentioned the evergreen distinction in my first post. There is a lot more going on with the AHS categories of dormant (soon to be changed to "deciduous"), semi dormant, and evergreen. Depending on growing conditions, cultivars registered as dormant may act as semi-evergreens, semi-evergreens as dormants or evergreens, and evergreens as semi-evergreens.
In order not to get bogged down, let's stick with the AHS designations.
There are a few conscientious southern hybridizers who send evergreen seedlings or registered cultivars to northern growers for hardiness testing. I know that Mark Carpenter does this with at least a few of his. I wish more did.
