Menyanthes trifoliata (Menyanthaceae)
BOGBEAN, BUCKBEAN, MARSH TREFOIL
The bitter leaves of bogbean,
named for its boggy habitat and bean-like leaves, are used as an alternative
to Gentiana lutea and for rheumatism, indigestion and anorexia.
The "bean" part of the common name reflects its typical legume-shaped leaves. Native to Europe, where it grows in shallow
boggy waters, it is a perennial with a creeping rootstock, clover-like leaves, and shaggy white-centred flowers with pinkish outers in midsummer.
