Just moved house and have a lot of what I believe to be the above. I want to keep them but not sure if they are annuals or what? How do I treat them? Lovely spikey yellow flowers about three foot tall.
Lysimachia clethroides has white flowers, so your ID seems to be wrong. Do you have a photo?
Lysimachia punctata springs to mind
Google it Jenny and see what you think.
Lysimachia is a perennial and comes in yellow, white, purple and short or tall depending in the variety. If you google it, you should get several images to help you identify what you have.
If it isn't any of those, take a picture of what you have, use the tree symbol to load it on here and someone will surely recognise it.
As Hosta says. be careful though, they are somewhat thuggish, and will make a bid for world domination, if given the chance.
Just had another look in book and they are lysimachia punctata. Have a photo but can't see how to upload it?
They are nearly impossible to kill - I've got some growing on concrete! They are good fillers when you haven't got much, but you will soon start wanting more and better things. They are thuggish and spread by running roots. You will have to dig out every bit of these when you have had enough of them. It is sad when they are such willing plants that they are such a hard and uncompromising yellow!

sorry obelixx, just doubled up on the tree icon advice.
Clethroides was a favourite plant in my previous garden, but my current place is a bit too hot and baked for them, so all I have is a memory and the nice photo below. I am trying Ciliata Firecracker, but it is sulking, as it's not quite moist enough in my garden.
Lovely photo Keen, Firecracker, in my experience is even more of a thug than punctata.
