Lysimachia
I have a clump of Lysimachia or Yellowstrife that seems to grow bigger every year despite attempts to keep it in check. I usually dig out large clumps of it but it just regrows with a vengeance. I have a feeling that I'm going about it the wrong way... Any ideas please? Thanks.

That's what it does sioned, I think you're doing the right thing. It's a bit of a thug for the average garden,
In the sticks near Peterborough
I really dislike the yellow lysimachia but I like the white version - clethroides alba aka gooseneck - as it has pretty white flowers in a bent cone shape that resemble a goose's neck. It's also vigorous but not as much of a thug as the yellow one and Fircracker has proved not at all invasive so far in my garden but there are better ways of getting the deep purple foliage without the nasty yellow flowers.
It was given to me by a dear friend so removing it completely would be a bit awkward. The one I have is the one with green stems - although I have the dark stemmed one too which I'm not too fond of either! Thanks for all the replies.
I suggest then that you dig it all up and replant a bit in a difficult corner where it will cope better than something that might struggle in poor light or poor soil. That will help control its vigour a bit. Bin the rest.
If you haven't a difficult corner, get a deep plastic pot as wide as you want it to grow, remove the bottom and bury it to its neck in the border. Replant a bit of your lysimachia in that and it will keep it under control.
Thanks obelixx! The pot idea is just what I need!
