A venerable heavyweight in the ornamental woodland plant world, Black Cohosh is a rhizomatous perennial native to rocky mesic woodlands of the Eastern U.S. Large lacy foliage holds its ground until giving rise to white, bottlebrush-like flower spikes in early summer, sometimes towering up to 8 feet tall! The tip of the inflorescence always seems to dip and twist to the side, as if waving hello on the summer breeze.
