Safest is to wait and plant in spring but only if you have a good place to over winter and will pay attention to their needs. You need some place like an unheated garage that stays between about 28-50F. Too cold and the plant may freeze. Too warm and it may start growing before last frost.

Ok I do have a basement that is unheated I could keep them in. I would sure hate to plant them and lose them. I think the basement would be ok temp wise and if it got colder than that we could bring them up into the house if need be for a couple days. Do you know what temps outdoors would be a good time to bring them in for winter?

Bring in after the leaves drop but before real cold. Be prepared for them to start growth before you wish. Don't bring them upstairs, that will be too warm. They won't freeze in a basement.

Thanks so much for the help!
