Can anyone help me to identify a plant I have growing in my garden - see photo attached - its very vigorous and spreads but when in full bloom its very pretty, my neighbours have been asking for it for their gardens but we dont know the name

Lysimachia punctata to be exact. And an awful thug where suited. Your neighbours may end up cursing you.

Just been trying to eradicate some that strayed into my garden from next door.

There's a red leaved one with the same flowers but less of a thug which is prettier too.
