Could indeed be a climber, a bit of a mystery. I have had this rose for two years now (zone 6a/b) and the first year it produced a very thick, long cane. Unfortunately it was broken by a neighbour's dog before I could fix it. I also did not expect that to happen, so I did not know what to do with it. It was so thick and long that it looked completely out of place for this rose (which was not supposed to be a climber). The second year I kept an eye on the new growth but nothing of the sort happened. The rose kept its small, delicate shape, with thin and rather short canes, elegantly spaced, nothing resembling a climber.
