I don't remember mine going fully red but maybe it does. Tim, agree that our plants look the same whatever they are!
I received mine from Cliff (@cahac) and he received his from SMG more than 10 years ago.
Just an update to keep this alive. Might as well get a year's worth of observation to make a decision. Actually, two years would be better but if we did that for every suspicious cultivar, there would be little time for anything else.
