You live in a tough climate for many plants. I thought mine was cold! Have you considered containers? Plant in at least a 16-inch diameter pot and put the rose bush outside after night temperatures stay above 30F. A south exposure will give you more heat, as will mulching the container with white pebbles or turkey grit, which is crushed oyster shells. You can store pots in the basement after they drop their leaves in fall. No light needed, as the bush will go dormant. Water the container every 3-4 weeks to keep the roots hydrated. I do this with a number of perennials that die in my winter, like bananas, hibiscus and a fig tree.
