What is this?

Hi just posting to see if anyone knows what this plant is? i tried getting rid of it last year but its come back again and i dont want it to its really invasive and its popping up all over my border.
Any ideas?
Thanks

 

Platycodon maybe? Did it flower?

 

no i havent seen it flower just seems to be foilage

 

Hi xNattyx, just looking back and found your post. This looks to me like Lysimachia, Does it have yellow flowers in the summer? It can be very invasive and take over if you don't keep keep dividing it

 

Yes i think JoF has got it ....I think the common name is Loosestrife...
