Red Baneberry (Actaea rubra),
SongofJoy wrote:
Native to rich woods across Canada and the northern half of the United States, Red Baneberry is the red-fruited counterpart of Doll's Eyes, Actaea pachypoda. Plants are long-lived and trouble free, forming 2 ft. clumps of twice or thrice cut leaves like very coarse fern leaves. One-half inch, puffy, creamy white spring flowers mature into clusters of bright red, poisonous, bitter berries, unlikely to be eaten by birds or humans. The berries persist into late summer. A plant for deep to partial shade and good soil. (Sunlight Gardens)
