Well I couldn't help myself... I recently purchased one of these trees and I'm waffling about what to do with it, given that it's just borderline hardy in our area. Has anyone managed to over-winter one that's been planted in the ground in the lower mainland of BC through a particularly harsh winter? I'm in the South Surrey / Crescent Beach area where we tend to get away with pushing the zonal boundaries a little more than most of the lower mainland (and I have a tendency to try to push it a little more than most). Would I be better off trying to keep it in a pot?
