Caulophyllum (Berberidaceae)

thalictroides ssp. robustum

From dry mountain woods of the Far East, having in time a stout rootstock, forming dense clumps of erect stems to 80cm. The broad spikes of greenish-brown flowers appear April-May, above the dissected broad foliage, followed by glaucous blue berries. Best in a leafy soil in full-part shade.
