Welcome to the Forum. Just something to keep in mind. As it sends up canes (which will have to be supported,) and it will, you may want to think about training a couple to the first rung, perhaps going in opposite directions to each other, all along that first rung. Then allow two more to reach the second rung, and consider the same thing. As you are aware, the more horizontal trailing canes vs straight up, the more flower buds. Just check "espalier" when you get a chance, It may be of interest! PS. Great Rose!! Cheers!
