Dusty, do check into any of the viticella types, these would be a very good choice for a partially shaded location. The viticellas always bloom their heads off!

Hi Margie! I usually have zone 4 winters but have seen minus 45 F. temperatures and had -39 F. several years ago. My trumpet vine dies back to the ground in these temperatures but resprouts in the Spring. If fact, they are hard to kill. On a good year when the temperatures don't go below about -20 F. the vines may be OK and even give you a few flowers, but I have not had too much luck with getting many flowers, so have resorted to clematis instead. I do have a wisteria good to -40 F. (Blue Moon) that you might consider trying to grow in your area.
