ID pleasePlease could someone please tell me what this plant is?

Lysimachia punctata by the looks of it, common name yellow loosestrife. Seems a bit late though, ours finished flowering 3 or 4 weeks ago - might just be geographical weather differences though, I'm in the south east and you're in west midlands...

I think it's also called Bee Balm. It's a spreader.

Bee balm usually refers to Monarda,also known as bergamot

Mine has just finished,here in Yorkshire..I also know it as Lysimachia,or Yellow Loosestrife. A good one for gap filling :o)

Mine are still flowering. As said it is a good gap filler but mine tends to send out runners in every direction in my garden. I just weed them out.
