I put a bareroot rosebush in the ground 2 years ago and last year it didn't have any buds, this year it has a lot , but they are a different color than when I planted the bush. The first rose on the bush was light yellow/pink/orange, this year they are dark pink/purple. This ever happen to you? 6-29-09 It turns out that Ron B was right. It is now the rootstock rose.
No, perhaps a branch has mutated to a different colour or maybe the stock plant was a different variety than the graft. Let us know if other branches are the same colour flowers or not. Interesting. :-)
'Dr. Brownell' died and was replaced by sprouts from the rootstock, 'Dr. Huey'. Kind of like at a medical clinic. You start off with one Dr. and end up with another.
