Bullace (one of many varieties of wild plum) in a Kent garden

This is an absolutely delicious wild plum. I found that Bullaces can come in red, green, purple and yellow. They are a bit smaller than most cultivated plums but larger than damsons and sloes. Mid July and perfectly ripe. My brother's garden in Bromley.
The one nearest the camera was eaten with much relish by yours truly immediately after taking this shot!
