What are these plants called?

As the evening wore on, and darkness descended, I realised that the opportunity to take a piccy in daylight had gone.  So I headed out into the garden with camera, mini tripod and a couple of £1 LED torches.  As it turned out, the camera wasn't able to compensate for the torches shining directly onto the plants but I eventually managed to get a blip that didn't have a totally bleached out subject.

If anyone knows the name of this weed/flower, please let me know.
