Real or no real!

I saw this pink hawthorn blossom on my way back from the allotment, I have seen tinges of pink on hawthorn before but not like this and with a double flower so I think it must be a cultivated variety trying to sneak in among the wild hedgerow, anyhow, it's pretty! Incidentally I discovered at the allotment that our Greengage trees has some greengages on......very exciting!
