The more I look at the shared pics of the rose, especially the one by Strever, I am sure that was my rose. I remember the outer side of the petals were that strong yellow with a hint of the orange/pink in the veins. I may remember it being a bit more gaudy, and multi colored, but I think that is pretty much exactly the way it looked. The pictures don't do it justice! I wonder where I can find it? I'm thinking too, that if the canes were not pruned, and it did have side shoots with the flowers on them, it may have been sold as a shorter climber. The side branches weren't like a "Blaze" or other climbers that really fill in thick. The canes were long, strong and straight. I'd curve them onto the fence in a fan formation, kinda, if that makes sense. It had a number of branches coming from the base.
So, can a strong and tall rose, be pruned shortly after grafting onto the root stock, creating a fan of branches that if not pruned will keep getting longer and appear like a climber, but not exactly like a normal climber? I have a very vague recollection that it may have been sold as a short or limited climber. Since I didn't prune the long canes, they just kept getting longer. It only took a couple of years for it to be really tall and long and glorious!
