Actaea racemosa (Ranunculaceae)
It is such a pleasure to come upon this understory perennial while hiking along the Blue Ridge Parkway, where late-summer woodland areas are lit up with multiple wands of pure white flowers. Give it plenty of room at the back of the border. In time, Black Cohosh can top out at 4-6' -- a dramatic and architectural presence. Partial shade with steady moisture keeps her leaves fresh and green. A variety of pollinators flock to the flowers. (Formerly Cimicifuga racemosa.)
