Facts

Red baneberry is a circumboreal species that inhabits rich, moist forests throughout New England. It is an attractive wildflower, whose shiny red fruits make it a great addition to the native plant garden. There is a much less common white-fruited form (Actaea rubra var. neglecta). The fruits of both forms are poisonous. Native Americans made much use of the roots in herbal medicine and as a ritual plant.

3.  Actaea rubra (Ait.) Willd. N

red baneberry. Actaea arguta Nutt.; A. spicata L. var. arguta (Nutt.) Torr.; A. spicata L. ssp. rubra (Ait.) Hultén • CT, MA, ME, NH, RI, VT. Forests, usually mesic, deciduous types, often associated with rich soils. White-fruited plants (forma neglecta) are much less common than red-fruited plants.

1×3. Actaea pachypoda × Actaea rubra → Actaea ×‌ludovici Boivin is a very rare baneberry hybrid known from MA, VT; also reported from RI by George (1997), but specimens are unknown. The hybrids are variable and show different combinations of character states (e.g., white berries on plants that appear close to A. rubra but also show more prominent stigmas and less pubescence on the abaxial leaf blades, red or pink berries on plants that appear close to A. pachypoda but also show more pubescence on the abaxial leaf surface). These plants frequently show some sterile fruits.

Native to North America?

Yes

Sometimes confused with

Actaea pachypoda:
berry usually white (red forms are common in some areas), on a thick stalk 1-2.5 mm in diameter, and stigma wider than ovary (vs. A. rubra, with the berry usually red (white forms are common in some areas), on a slender stalk 0.3-0.7 mm in diameter, and stigma narrower than ovary).
