What is this please?

This attractive plant appeared this year in my fern patch and I wondered if anyone can tell me what it is. I'm hoping its not something invasive. It stands about 3 foot high with a strong, slender stem. The centre of the delicate pink flower is yellow.

japanese anemone , I'd use the word "invasive" . Spreads way beyond its allotted space IMHO.

Oh dear, I suppose it's going to have to join the throng of ground elder roots I shall be digging out of my fern patch later this year.

and, like ground elder, every bit of root you leave behind will regrow

Thanks for the warning Hostafan.

 I have the same one, it’s well behaved here, it’s been here 30 years! 
Ok, it was only one pot when my dad planted it but the bees love it and so do I, I would never get rid of it.

Mine doesn't spread at all. I wish it would.

Totally agree, I grew them once and never again. It spread everywhere, came up under the patio etc. The flowers are lovely but it's just too invasive and also hard to dig up.

Certainly  not for me!  I’ve put a root of it somewhere else, been for 6 years and still well behaved.
Or is that not what I’ve got in the above photo?

It looks like one to me @Lyn ! 
Maybe l was lucky, because they did spread a bit but l managed to pull them out quite easily and they didn't return. It may have something to do with the fact that there is a quite a solid "pan" about 18 inches to 2 feet down.

I wish mine would spread a bit.
