I think this is a lysimachia and most probably clethroides or a form of that.
Note the left hand flower in the top picture, it's bent over.
I've just been and looked at mine, they start straight and then bend over. The flowers and the alternate leaves up the stem are right as well
L. clethroides is a herbaceous perennial, not a bush, whatever it look like in a picture
