Frogbit Hydrocharis morsus-ranae

An attractive perennial aquatic plant which floats on the surface of still, shallow water bodies like ponds, lakes, ditches and dykes. The main stems are submerged but not rooted in the substrate dropping to the bottom at the end of summer where the plant remains dormant for the winter.

Conservation status

It is listed as vulnerable but locally common. Numbers are declining in Britain due to the loss of grazing marshes and eutrophication (the enrichment of the water by nitrates and phosphates from agriculture and domestic run off).

Details

Did you know? Reproduction is vegetative rather than by seed; it produces buds on the runners which detach in autumn and sink to the bottom of the water and in spring they float to the surface to produce a new plant.

The classical Greeks believed that the plant was eaten by frogs because it disappeared at the end of summer.
