Ceratostigma plumbaginoides.
It looks like Ceratostigma willmottianum aka Chinese plumbago to me
I can't see the over-all shape of the plant but the taller stems on the top left suggest C. willmottianum to me
In the sticks near Peterborough
That's what I though Nut - looks exactly like the one in my border

This might be a better image of it. It must have come from one of those mixed packets of seeds, Thompson and Morgan - else via the free seed from birds!

A lovely thing. I bought mine from the 'nearly dead' section at the GC, and it still cost me more than a fiver a couple of years ago.
Wow, glad I have collected the seeds then!
