Roxanne is a nice mannerly plant. I can't use it around my roses because I can only grow it in the shade here.
I have three of the roses that you're traiing as pillar roses. Lady Ashe (more commonly known as Dixieland Linda) and Stormy Weather are particularly good candidates for this. Reine des Violettes is too bushy for pillaring in my garden. I use velcro garden tape to tie up roses and vines. It never cuts into the plants, and it's green, so it virtually "disappears" in the plant foliage.
