Water Plantain

• The water plantain (Alisma plantago) is found in bogs and ponds throughout Britain. It thrives on shorelines, either in sopping soil or in water up to 6 inches deep. This plant bears green, arrow-shaped leaves on erect stems 3 feet high. In the summer it produces small white hermaphroditic flowers, which are pollinated by flies. The fresh leaves and roots of the water plantain are poisonous to humans.
