Regarding freezing, they do fine in the landscape with freezes. In pots I know they have a little twig dieback in freezes, but the roots ought to be fine. I currently have 3 crapes in cement mixing tubs sitting on the ground. We're expecting some light freezes this weekend and I doubt I'm going to move them ...since each of them are larger than the one posted and cumbersome to move. I think they'll do fine, though its wise to protect from hard freezes.
I advised the protection from freezing only because it was recently collected.
