Pissard's Plum

I wasn't going to blip today, but I walked down to Cranham Village (as they call it) and saw about five of these trees in beautiful flower. This was the fattest. I think they must predate the front gardens. I thought I had seen one on Paul Wood's Instagram feed recently and sure enough here it is @thestreettree. The reason I know what he means about the colour is that I found it on Google Street View, apparently a couple of months later, see first extra.
Tesco in Cranham has recently been done up, and the second extra shows that we pedestrians are not allowed to walk through the remaining hole.
