Hello, and thanks for using the Ask an Expert System.
The rose bush in the photo is a typical grafted rose. That is the red flowering bush is grafted onto a vigorous, disease resistant root stock. Ordinarily the rootstock does not produce stems and flowers. However under certain condition you will get both stems and flowers from the root stock. It is best to remove the root stock stems since they may overgrow the original and larger flowered red rose. I am attaching a link to a video that explains the best way to identify and remove root stock stems. https://www.youtube.com/watch?v=wQVIlLgfTWg
