The generic name Menyanthes probably comes from the Greek menyein, meaning disclosing, and anthos, meaning flower.
Plant Description
Bogbean is a rhizomatous emergent aquatic perennial plant that grows up to 15 to 30 cm in height (above water). The plant is found growing in various wetland habitats such as fens, pools, marshes, older woods, ditches, bogs, lake shores, swampy prairies, particularly in acid or oligotrophic conditions. Roots are thick, creeping and can both be attached to the ground or may be free-floating in water. Flower stalks and leaves rise well above the water surface from thick creeping rhizomes that spread indefinitely. Trifoliate leaves are alternate, long-stalked and have three elliptic leaflets. Leaflets are stalk less, elliptic–obovate, with entire margins, glabrous. Leaflets are 1½ to 2½ inches long and to 1 inch wide, becoming larger later in the season. Flowers are star shaped, five-petaled and fringed with extravagant white, cottony hairs which have a pinkish flush on the outside of the petals. Flowering normally takes place from May to July. Fruit is spherical, 1-parted, many-seeded capsule which contains numerous 2-3 mm long, lens shaped, yellow seeds.
