Well, I know you've recommended GB to me in the past, so I thought I would post what I knew about containing thorny or floping roses. I know the once a year trim out of my old Stanwell Perpetual hedge almost required a Kevlar suit! It is interesting to note that GB's coloring is best in cool temps as most of my temps are not cool at all (barring this past spring--which has been highly unusual). And, crazy me, I've just bought a Stanwell band to grow out and peg so that I may have many more tiny Stanwells to start a new hedge! I just can't resist having another.
