Hi Sunflower. My Victoria Plum is doing the same thing. Posted a question about it a few days ago, but nobody has replied. I assume it's something to do with weather patterns. I'm just going to leave mine and see what happens. It's only a few flowers, but I've had a few more show and open since I last posted on this subject. Won't do any harm to leave them. BTW Victoria is not a new planting, it was there when I moved into the cottage 4 years ago and is a mature tree.
