Hi Diane,

I have about 800 plants in pots that I am overwintering in my insulated 
shop.  Roots can definately survive freezing temperatures, as they do in the 
frozen ground, but only to a point.  Every type of plant is different, but I 
have a heater in my shop so the temperatures don't go below about 25F. They 
survive every year in their dormant state, so you shouldn't have too many 
problems.
