You can bring it inside for the winter. Here is how to take care of it:

Well, you could try to overwinter it in your basement (or inside with no sun after it goes dormant, provide humidity (the inside of homes gets dry in the winter months) and away from air vents) but in my much warmer zone 8, a neighbor that was a frequent grower of Mandevillas experimented, gave up on overwintering and decided to just get another one every spring. The shrub would tend to lose all above ground growth in winter, grow back from the roots and it would take a while to regrow and then to bloom. She preferred getting a new one already in bloom that was blooming and significantly bigger than her overwintered plant would get by late summer.
