Sounds to me like you had a sucker from the roots and now it's taken over the entire bush. Hybrid tea roses are rose plants that are grafted onto roots from a hardier plant. Any "suckers" or growths coming up from the base of the plant that have distinctly different foliage from the plant you bought should be cut away, since they are canes growing from the roots which are actually the roots of a different plant. Make sense? If you don't cut away the suckers, they will eventually take over the whole plant, effectively killing off your original hybrid tea plant.

wrong wrong wrong. Please reread the question. All J & P roses are either own root or use Dr. Huey. Dr. Huey is Burgandy/Red, not tangerine. This is something else, which I am beginning to believe is RMV.
