Plant I.D please...pink flower

Hello everyone ...I'm new to this website but I'm confident someone will be able to help me. I have no idea what this is and have never even seen it anywhere else. That may be due to my short-sightedness of course! :hehe:

 

Is it a Stock perhaps?

 

It looks like Lychnis coronaria - will self seed all over the place....if that's what it is, grey foliage with pink/purple or whitye flowers.

 

It looks like Lychnis coronaria to me too. Its a biennial or short lived perennial, and flowers for a long time. I have still got some flowers on mine.

 

WoW! I can't believe how quick you peeps are! Well...I have looked at stock pics but none seem to match....so I'll look at some Lychnis Coronaria now....and by the way....I love it...so if it does self seed everywhere I really don't mind :gnthb:

 

:yez: that's the one...here's a link to a bit more info...Thanks very much to you all!!
