I'd say yes! I have a few white and I think it would look real nice to graft a deep red on to it, and while I'm at it, why not graft a white branch (which I cut in order to receive the the red) use that white and graft it on to the red. Verity I believe is the spice of life. Unlike Melissa I think that if you have many different plants, is all the more reason to graft some on to the others. Also, just to learn how to do it is fun.
