New to this forum but it seems the right place to ask my question..

Does anyone have experience with the climbing rose Dublin Bay? I'm specifically interested in knowing two things: (1) whether it is cane hardy in zone 4a/3b (can you leave the canes in place over the winter?); and (2) whether the canes are flexible enough to train horizontally along a rail fence.

Thanks for whatever info you might be able to share!
