|The Smooth Prince Thornless Hybrid Tea Rose is only considered winter hardy into USDA winter hardiness zone 6. Based on your zip code you are gardening in zone 4, that is substantially colder than this rose can withstand. So I would not expect this rose to survive the winter outdoors, even with winter protection. I'm sorry I can't be more encouraging.
