what is this flowering plant called?

It's only just started to flower so there's only the one pale pink bloom to test your expert knowledge! (and it's being nibbled by the insects too)

Japanese anemone

Oh yes we have this too and had forgotten its name!

Japanese anenome. It spreads by underground runners & can take over if you don't keep it in check.

Mine is 8 years old and hasn't taken over yet. It isn't the most invasive plant but it's a doddle to grow and very pretty.If it gets too big divide it up and give you friends a clump. Try not to dig the whole thing up as they don't like to be disturbed.
