A stoloniferous perennial herb which grows in fens and marshes, on ditch, canal and pond edges, around reservoirs and in flooded gravel-pits and quarries. It is normally found in base-rich, still or slowly flowing water. Lowland.
The 1962 Atlas illustrated the decline of native R. lingua in Britain, a result of drainage over the last two hundred years. Since 1962, however, the situation has been transformed by its increased popularity as an ornamental plant. It is frequently introduced to ponds and other wetlands in the wild and the distinction between native and alien populations is now hopelessly blurred. In Ireland the native plant is still locally frequent.
Eurosiberian Temperate element.
