Bogbean (Menyanthes trifoliata)

Where?

Bogbean (Menyanthes trifoliata) grows in shallow water and spring swamps of rivers, in fen forests, intermountain fens, and on edges of upland bogs.

Appearance?

Bogbean is a perennial, herbaceous plant that grows up to 30 cm tall and forms rhizomes up to finger-thick, from which 12 to 20 cm long leaf stalks grow, each with three elliptical, smooth leaves. From April to June, inflorescences form on the leaf axils on up to 30 cm long, leafless shafts, with, per flower, five pink to pure white sepals.

Special Features?

Bogbean has been used as a remedy and is said to help with digestive problems. However, the originally assumed fever-reducing effect cannot be proven. They can cause headaches, vomiting and diarrhea.
