Thanks Dorts, I'll look up those sub-species. The tendency to interbreed will explain the arrival of my own Cherryplum. I have Plums,Damsons and Sloes close by so will be propagating the next stones with interest. The bush in question has taken about six years from sowing to fruiting and is more vigorous than the blackthorns which came from the same sowing. None of the seedlings have produced Bullaces as yet. My bullace wine seems to take longer to clear and the flavour is odd, but after a few glasses one hardly notices !
