Answer: Most commercial roses are grafted onto a different rootstock at a joint called the "bud union." This is because the rootstock usually offers some advantage such as resistance to insects, disease or greater vigor. It sounds as if the floribunda itself may have died and the rootstock has sprouted and taken over. I don't think there's anything you can do to revive the floribunda at this point. I hope that you like the pink rose! Thanks for writing!
