    Life History

    Perennial aquatic plant. In the summer when it flowers, this plant floats on the water surface with the leaves just above the surface. In the autumn they become covered with a slimy secretion (calcium carbonate) and the whole plant sinks to the bottom to rise again in the spring. It is a native UK species, but many plants found have escaped, or been discarded, from garden ponds.
