Answer: You might look into the Explorer series of roses developed in Canada for exceptional hardiness. The taller roses in this group such as William Baffin, John Cabot and Henry Kelsey are often grown more or less as climbers and trained to arches and such. Keep in mind also that the healthier and more robust the plants are during the growing season, the better they seem to tolerate cold and adverse winter conditions. So try to site them in a good location (full sun but protected from wind) and take good care of them during the growing season for best results. Your local chapter of the American Rose Society may also have some suggestions based on local experience as to climbing type roses that might do particularly well in your microclimate. Good luck!
