I wanted to put my input, though I will need your eyes to do so. If the pink flower is on a separate stem from the second 2 photos, I think this would need to be cut back to the ground to keep the entire rose from reverting back to its original stock growth (or sucker growth). Those flowers are weaker, smaller, and not as fragrant. Now if the pictures are all from that one flower . . . ok, then you have me stumped!! Gorgeous. But do check to see if the pink one is on a separate branch. Enjoy!!
