This rose was growing in a planting bed when I moved into this house. It puts on beautiful flowers on a very unattractive plant. I'd like to give it a generous pruning but of course I'd like to know what it is so I can do it properly. I have *no* experience with roses. The home is 70 years old so this plant may have been here quite a long time - the stems at the base are enormous. I have removed a few dead sections to improve its appearance but the whole plant needs reshaping. Is anyone familiar with this cultivar? Thank you!
