The Q&A Archives: Color Change In Roses

Question: My three year old yellow floribunda rose bush appears to have changed color! Last year this bush apeared to be dead, she did not come out of hibernation (canes remained brown) until well into the summer, July-Aug, and produced no blooms. Now, this bush is growing like crazy and today she has PINK blooms! What is happening?

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!
