SL it's Lysimachia. It's been discussed on forum quite a bit lately, some people do find it a pesky spreading thing. It seems to behave where we have it as it's not a very hospitable area for growing. It's in a really drafty cold area.
p.s.we don't light the chimnea there, it's currently in the naughty corner as it's gone rusty and was making a mess on the patio
