Plant ID, please.

Hi. What's this plant, please? I've found it sprawling itself over walls and fairly neglected areas. They look like spring flowers but it's flowering now. The pictures are the whole mass, a close-up of flowers and a close-up of leaves.

Russian vine aka mile a minute plant and an absolute bastard

Looks pretty but very invasive. Plant it at 10 am and by teatime its knocking on your door

Ah, thank you. I guessed it was a baddie because it's so profuse. It's v pretty though; excellent for real-flower confetti.

“Plant it at 10am and by teatime it’s knocking at your door”. Brilliant expression which I shall borrow from here on!

Yes, it's not called 'Mile-a-Minute' for nothing...

Avoid like the plague.
