Bogbean
Menyanthes trifoliata
Bogbean
This plant is considered eradicated in New Zealand.
Description
Bogbean is a perennial plant that can grow in bogs and marshes and at the fringes of lakes or slow- flowing rivers. Bogbean has a creeping rootstock and thick green stems that often trail along the surface of the water body. It has very characteristic three-lobed light-green hairless leaves that emerge from the water. These die back in winter. In early summer long stalks bear pale-rose-coloured flowers (2.5 cm across) clustered together in a thick short spike. The inner petals are white and hairy, with reddish stamens. The flowers produce round orange seeds.
Impact
Bogbean grows rapidly and clogs waterways.
