Do the leaves smell when you crush them?
It looks like the first year rosette of jack by the hedge. Alliaria petiolata. Stinks of garlic. You can cook it.
That's what it looks like to me.
Hi fidget. just been for a crush and sniff! Smells a bit oniony.
Hiya. You responded whilst I was out sniffing! Sounds like thats this thing. Much appreciated.
