|No. It's a great rootstock, and depending on your climate and soil type it can be the best. Unlike rootstocks such as 'Dr. Huey' or 'Manetti', 'R. multiflora' is a species rose that will breed true by seeds. All non-species rootstocks are propagated from cuttings and other rose viruses (such as the group of viruses lumped under the symptom name rose mosaic) can be transmitted by grafting onto infected rootstocks. Once one cutting is infected, all its offspring will be as well as all the rootstock used with each and every budeye. Those viruses are not transmitted through seeds, so when clean budwood is used on multiflora grown from seed you are guaranteed a clean plant.
