Help identifying a plant ...??

Hi
I'm hoping somebody can help me identify this plant.

He came with a batch of Sweet Williams (which on one of the photos you can the foliage of ...) When planted, i thought he was a Sweet William HOWEVER, as he's grown to approx 3 foot and seems very different ... I'm not sure what he is ...

He's 3 foot or so
Sparse foliage, almost wispy ...?
Very small pink/light purple flowers
Lower leaves are now turning red
A very strong plant. I live on the coast, so most plants I have to stake ... This one is doing fine without ...

NB (on one of the photos, there is a cosmos ... The plant I am referring to is on the right ...)

Any help would be very much appreciated ...

Kindest regards from me and my green fingers!!!

Sorry Chris, but it's a weed (sorry native wildflower) one the the Willow herbs - Epilobium. Those long thin pods are full of seeds so I'd pull it out asap to stop it spreading all over your garden.

Many thanks for the quick response Sue ... I had suspected it, but seemed so unusual that it grew 'on its own' if that makes sense ...

It's almost 11pm ... But I'm on my way out now to get rid!!

Cheers

that's why weeds are so good at spreading, they are brilliant at 'growing on their own'
