We have had this rose for about 6 years now. It has grown and bloomed every year, but in general never done very well, probably due to the huge amount of Japanese beatles we have every summer and the harsh temperatures in the winter (Vermont, zone 4) I have forgotten the name, the color is light pink, when the blooms are open all the way it is pretty much almost white. I prune it every year, it is NOT grafted. On the branches that it has had light pink to white flowers on every year it now has dark burgundy buds. I am stunned to say the least. I knew that minerals can change the color of hydrangea but roses??? Does anyone have an explanation for this?
