Hardiest Climbing Roses??
Hi... I was wondering if anyone could tell me from experience what the hardiest climbing roses are? I've ordered Polestar, Cape Diamond, Louis Jolliet and John Davis. I was going to purchase Alchymist, but the greenhouse staff said it wouldn't survive here. Does anyone have experience in the far north with the 4 climbers I am trying? Also, is there a yellow rose hardy enough for the far north? We can usually plant anything that grows in zone 3, but J.P. Connell and Morden Sunrise which are listed as being hardy in zone 3 are not advised for Fort McMurray.... what's up with the yellow roses not being hardy?
