Astrantia 'Ruby Star'

Still finding it hard to work out what all the plants in our garden are called. We have a detailed plan, but the contractor seems to have put most of them in different places to the plan. I think when they arrived the garden designer laid them out according to his inspiration on the day, which is fair enough I guess as seeing the garden in the flesh is not quite the same as seeing a drawing on a piece of paper.

I think I got this one right with a bit of help from Google, though it's not where it should be.
