Lesser water-plantain can grow in water as well as dried pools. The ripe fruit can contain as much as 50 individually wrapped seeds. This can make the plant top-heavy. Should the seeds come in contact with water while still on the plant, it's possible for them to germinate. Lesser water-plantain often grows in combination with shore-weed and brookweed in dune pools which lay dry in the summer. It is fairly common on the Wadden Islands and in Voorne, however it has become a rare plant in other parts of the Netherlands.
