I layered this from an old plant on an vacant lot- the bush has two different colors. The first is the layered one and the second is from the other half of the bush- is this a mutation or is it just enviromental? Actually one half was all pink and the other was the white striped that you see. The layered one seems to be in between. This is from a single plant- I checked just to be sure. It doesn't seem to be from the understock either. I really liked the striped one better though.
