Allotments 4 All

What is this? I have two growing in my garden. And, perhaps more importantly, do I want it growing in my garden?

Ma in law used to have something like this in her garden.  Dont know what its called but it used to have amazing cerise flowers.  Sorry not much help but Im sure the name will come to me.  Probably around 2 am  :P

looks like Lychnis coronaria or Rose Campion to me.  love the wild Lychnis and Silene but don't much care for rose Camion....

Possibly lychnis coronaria, which comes in shocking magenta or white:

Or maybe centaurea montana:

Thanks!

I'll leave it and see what it does when it flowers. If it's pink, it'll be on the compost PDQ!

 Rose Campion i would say

Looks like Stachys Byzantia - Lambs Ears....are the leaves soft and furry? I can't make out from here....
