What is this?

[Excitedforxmas]

I remember only planting fruit trees in one area of my garden once upon a time but some years later nothing has ever grown on this. It's really prickly and has white flowers on and this year it's growing like wildfire .
Anyone any ideas?

Looks like blackthorn (Prunus Spinoza). Could you have planted in hopes of making sloe gin?

Yep looks like blackthorn. Lucky you - your very own sloe supply!

Gawd no not that I remember. thought I had bought redcurrent and blueberry!
Thanks so much
