Buckbean (Menyanthes trifoliata) is a native wildflower that grows in bogs in the Adirondacks of upstate New York. Its star-like, white flowers appear in late spring.

The scientific name "trifoliata" is a reference to the fact that the leaves consist of three leaflets. This plant is also called Bogbean. The common name refers to its small, bean-like seeds.

Buckbean grows up to about ten inches tall. Its leaves are stalked. At the top of the leaf stalk are three smooth, rounded leaflets about 2.5 inches long.

Buckbean produces clusters of white or purple-tinged, star-like flowers emerging from stout stalks. Each flower is about a half inch wide, with five or six pointed lobes covered with short hairs, giving the flowers a fuzzy appearance. In the Adirondack region, Buckbean flowers in late May and early June.

Buckbean fruit is a capsule, with many small, hard seeds. The smooth, shiny seeds are bean-like, giving Buckbean its common name.

Uses of Buckbean

Buckbean has been used as both a food and a medicine. In Europe, the leaves were sometimes used as a substitute for hops in beer brewing and were also boiled in honey to make mead. Powdered Buckbean roots were reportedly mixed with flour as a bread additive.

Various medicinal applications of this species have been recorded. Buckbean has been used to treat many ailments, including jaundice, indigestion, skin diseases, scurvy, intestinal worms, and rheumatism. Small doses of this plant are said to impart vigor to the stomach and aid digestion. However, large doses may cause abdominal pains, nausea, and vomiting.

Wildlife Value of Buckbean

Buckbean has limited wildlife value. However, it is part of a wetland environment that is critical to some species of birds. Buckbean is found in bogs which form an important breeding habitat of a number of birds including:

Distribution of Buckbean

Buckbean may be seen in bogs from Labrador to Alaska, south to Virginia, Missouri, and California.

In New York State, Buckbean is present in most counties in the eastern part of the state. With the exception of Saratoga County, Buckbean is found in all counties within the Adirondack Park Blue Line.

Habitat of Buckbean

Buckbean grows in bogs, poor to rich fens, rich swamps, and cool springy forests. It flourishes in wet soil or shallow water on the edges of ponds and in marshy ground, usually in acid soils. This plant is found in several ecological communities in the Adirondack Park, including Medium Fen, Red Maple-Tamarack Peat Swamp, and Rich Graminoid Fen. A convenient place to find Buckbean is on Barnum Bog, which can be accessed from the Boreal Life Trail boardwalk.
