Lysimachia - Clethroides

Its a beauty Olive....unusual

Only bought it this year, am hoping it spreads as it is supposed to be quite a bossy plant. Fingers crossed I don't mind controlling it I need it to fill in a space left when I chopped out a white Buddlehia which was getting out of control, even though I chopped it down drastically each year. It threw up lots of branches and got too high so it had to go. I did replace it further up the garden though with a dark blue one. The butterflies love them.
