Possibly Astrantia Bavarica.

Thanks sophiemears, I looked up Bavarica but, although the flower is the same in one pic, the leaves are different - (or at least in the photos on the web) all to large. it gave Bavarica's height at 1ft, this plant is max 3 to 4ins in height.I will post photo of the leaves.

Have a search for Astrantia Minor. I expect you'll find it there with a bit of luck. I love astrantias, stunning flowers which last for weeks.

Thanks for all your help Sophiemears, it does look like Astrantia. minor.
