Sanguisorba hakusanensis aff, (possibly)

This is a weird one, it is about 50cm tall plus some for the lovely blooms. The clump of burnett like leaves erupt with a multitude of arching stems,  each carrying fluffy pink rabbits' tails which are about 50mm long. Easy care, sun or part shade. Photo seemed to be the one, so here is an image from wikipedia courtesy: 利用者:Σ64. Mine is shown in the second image.
