The "Body Bag" Rose

This is a new term I learned on I believe, GardenWeb. Of course, invoked derisively. I bought two last year--why? unclear. One died, but that's not surprising as I treated them, uh, poorly. This red climbing rose wasn't having any of it, and has returned, as you can see, quite vigorously. What is it? Wish I knew. I have made a point of saving all plant tags to reference, and I seem to have them all...except the ones I really need. At this point, I'm doing my best to contain this sucker. (To my credit, I did transplant this this spring, ammend with bone meal and fertilizer, and mulch well. Beyond that, I think the conditions--i.e. where it is on the deck--are ideal, kind of by accident. The thing is, I'm going to move it...)

Lean & Green!
