A gardener's 4-year-old pink cluster-blooming rose suddenly produced single red flowers and tall red shoots. They wanted to restore the original pink color.

Dr. Huey rootstock in bloom
Almost all modern hybrid tea and floribunda roses are budded onto a vigorous rootstock—most commonly 'Dr. Huey', a semi-double, dark red climber. The rootstock provides vigor, but if the grafted variety dies (from winter damage, disease, or late-season fertilizing that prevents hardening off), the rootstock takes over.
No. The original variety is dead. The plant is now entirely Dr. Huey. You cannot revert it. The only solution is to dig it out and plant a new rose of your desired variety, ensuring the bud union is buried 2–3 inches deep in your zone for winter protection.
