Thalictrum Delavayi 'Blizzard'

(Syn. Thalictrum dipterocarpum nana alba). An absolutely exquisite pure white variety of Thalictrum delavayi. This is more compact than the pink variety and produces thousands of small, shimmering, umbrella-like flowers, amongst delicate, gossamer-like, paler-green-than-usual, ferny foliage, right into late autumn.
