In August 2013, a good month before my damsons usually ripen, I spotted this extraordinary two-toned damson growing on an old tree:

Over several days I noticed many more damsons on different trees in that same ‘two-toned’ way.
I’ve never seen this anything like this before.
If you are a plant scientist and know what this colouring is all about I’d be grateful if you’d leave a comment and throw some light on this phenomenon.
