Japanese maples grown in a container in your zone must be overwintered in a protected location. That means a garage, unheated basement, greenhouse, etc. Just wrapping the pot is insufficient protection - temperatures that drop below around 26F can fatally damage the root system.

Otherwise, a lot of Japanese maples should do well in your zone in the ground - zone 5 is generally considered the lower cut-off for these trees but location and/or microclimate can extend that. Look at whatever JM's are available in your area - otherwise, check out some good JM's for colder climates, like in the attached link.

Thank you so much! If we do put a new maple in a pot, we will make sure it gets moved into the garage this time.

And the link is great! Now that we have some names, the search begins...

scroll though this!

Thanks to you both - I think we are going to get an Ogon Sarasa and put it in the ground, not in a pot. Any advice on where to purchase one in the area? We haven't had any luck so far finding one...ordering online is fine too, if anyone has a nursery recommendation.
