About this plant
A small carpeting plant that comes into its own in boggy places, or even growing in a few centimetres of water. It has light fresh green leaves that are plump and paired with pointed tips. They carry small round yellow flowers during the summer. It is a pleasant plant to mask the boundary between moist, bog and water, making a pool appear to be a natural part of its environment.
