a.s. aureum hardiness?
Holiday Greetings to All! I'm posting from central Virginia, where there is currently a light snowfall, and I have a young aureum outside braving the elements for its first year with me--it is potted in a clay pot on my deck and is now about eighteen inches to two feel tall. Considerable discussion between boyfriend and myself as to hardiness and when / if ever we should tote the plant into the garage. I would appreciate experience with hardiness. How cold must it be before I bring it in? Thank you very much, knowledgeable maple people.
