Being a relative newbie to Britain, I’m still very much a learner when it comes to identifying plants (and everything else, to be honest), so I was pleased recently to learn how to tell Cherry plum blossom from Blackthorn.
It’s partly in the timing – Cherry plum (Prunus cerasifera) usually flowers first, apparently – and also in the growth pattern, but a sure-fire way to tell whether the gorgeous blossom you’re puzzling over is this or Blackthorn (Prunus spinosa), which flowers soon afterwards, is to look at the back of the flower.
In the Blackthorn the sepals (those leaf-like bits that originally enclose the flower but split apart when the flower opens) lay flat along the backs of the flower petals, or between them when fully open (photos above), whereas in the Cherry plum, the sepals are folded back (photos below).

armed with your simple ID method for blackthorn and Cherry Plum, I went to my meadow where I have both to work out which is which! thank you very much for the observation. Blackthorn seems to be very late this year?

Good news! The Blackthorn hasn’t been late in my part of the world – maybe it depended on what winter weather we had.

Really helpful tip, thank you! Here on the Solent, the Cherry Plum (sepals curling back!) is flowering already – third week in Feb.

Glad it was helpful! Both are flowering here now … spring’s come (too!) early this year.
