Calling keen horticulturalists

This plant is flowering my local park. It is covered in honey bees at the moment. I am thinking of planting it myself, any ideas what it is?

Thanks

It looks to me like a variety of Bistort.

Thanks very much. Will see if I can propagate it by seed,

Edit: looks like division is best. Will have a word with my friendly park keeper...
