Prime Season
Spring to Early Summer Flowering



Baneberries are erect native perennial woodland plants, 1 to 2 1/2 feet high.

The leaves of A. rubra are oblong coarsely toothed, alternate, 2 to 3 times 3-parted leaflets, similar to the White Baneberry except some leaves may have some hair on the underside. The leaves all grow from the upper part of the stems leaving the lower stems bare and exposed under the leaves.

The inflorescence is a rounded cluster of small white flowers, on a long stalk, somewhat pyramidal in shape, but about as long as wide (but this is not diagnostic); rising directly from the leaf stem, at or just below the division point of the 3 leaf parts, and rising higher than the leaves.

Flowers are bisexual. The cream colored flower petals number 4 to 10, are ovate with an acute to obtuse tip and very tapered to clawed base. These fall off early leaving the stamens pointing outward in multiple directions. Stamens can number 15 to 50, and have white long filaments and cream anthers. There is one pistil with the style either very short or absent. The sepals of calyx are whitish-green in color, and are not persistent on the fruit.

Fruit: The lustrous berries may occasionally be white (photo page), but on this species, be they red or white, are each on a very slender greenish stalk which is dull green to brown at maturity, The fleshy berries are oval in shape and contain 8 or more hard seeds that are cone shaped to wedge shaped, dark brown to reddish brown in color. Seeds are difficult to start as they must have a cold moist period followed by a warm moist period and another cold moist period, which means if sowed outside, they will not germinate until the 2nd year.

HAZARD: Baneberry plants are poisonous and the berries are considered especially poisonous. More notes at page bottom.


Habitat: As it is a woodland plant Red Baneberry is found in shady spots of open woods and forests where there is wet to mesic moisture conditions. The root is a woody caudex with fibrous roots. Stems die back to the ground in the fall. The plants locations in the Upland Garden are mostly near Aster Aisle and the Fern Glen. In the Woodland Garden it will be found along shady paths.

Names: The genus name Actaea is the Latin name that was used by Pliny and adopted by Linnaeus. The Latin is thought to come from old Greek, either aktea or akte, for 'elder' which probably refers to a similarity of leaf type with that plant. The species, rubra, is Latin for "red". The common name of baneberry was applied in reference to the poisonous fruit.

The plant author names accepted today are two-fold: Modifying the work of Linnaeus and using the name Actaea spicata in 1789 was ‘Aiton’ which refers to William Aiton (1731-1793), Scottish botanist, who succeeded Philip Miller as superintendent of the Chelsea Physic Garden and then became director of Kew Gardens, where he published Hortus Kewensis, the Garden’s catalogue of plants. His work was revised in 1809 to the current name by ‘Willd.’ who is Carl Ludwig Willdenow (1765-1812), German botanist, a founder of the study of the geographic distribution of plants. He was director and curator of the Botanic Garden of Berlin.

Comparisons: A. rubra is similar to the White Baneberry (Actaea pachypoda) except that there the individual berries are each on a stouter, red, fleshier stalk, compared to the Red Baneberry where the stalks are much thinner and greenish; the flower petal tips are truncate or cleft; the raceme of A. pachypoda is more elongated but that is not absolutely definitive. The Garden staff has noted however, that the white berry form plants in the Garden have hybrid characteristics of both Actaea pachypoda and rubra.

Notes: Red Baneberry is indigenous to the Garden area. Eloise Butler catalogued it on May 25, 1907; in addition in 1910 she planted some plants that she obtained in Cokato, MN, and on July 11, 1912 more plants from Foley, MN. This plant was listed on Martha Crone's 1951 inventory of plants in the Garden at that time and she planted seeds in 1953. Susan Wilkins added plants in 2009, '12, and '13. Red Baneberry is native to Minnesota in most counties throughout the state except a few exceptions in the SW quadrant. It is found throughout North America except the SE quadrant of the U.S. from Texas east to the coast. A. pachypoda, the White Baneberry, is the only other species of Actaea found in North America.

Medicinal Lore: Tilford (Ref. #39) reports that clinical herbalists have found Red Baneberry useful as a strong antispasmodic. The root is considered a strong alternative to Black Cohosh as a herbal remedy for menstrual cramping and menopausal discomforts. Densmore (Ref. #5), in her study of the Minnesota Chippewa reports the same use but refers to the roots of those plants of the species which bear the white berries. The plants that bear red berries are said to be used for diseases of men. Care had to be taken in any case, as large quantities of baneberry consumed may cause cardiac arrest.
