2 type rose bush #203635

Asked July 31, 2014, 9:40 AM EDT

We have a very old rose bush that has dark red flowers, normal size, every year. Also every year down at the base among the stems, small white roses bloom. These are about the size of a dollar coin. Is this unusual for 2 different size and color roses from the same bush? To the best of anyones knowledge, the large rose bush was the only ever planted there. Noone remembers the white roses ever being planted in the exact same location.

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
