On second thought...
I just finished squeezing my RVR order into the garden. I find that there are these places where shrub roses that are supposed to grow to five feet in height are planted less than three feet from a nearest neighbor. Maybe I need to wait at least until the end of the season to contemplate getting more roses. Maybe some rose that I really don't like will die and need to be replaced. Can't think of an example. I'm guessing both own-root Don Juan roses are on their way out, though. Probably be replaced by Sympathie from Palatine.
