A perennial herb of wet habitats, particularly those with seasonal water level fluctuations. It is found in springs and flushes, around ponds, on lake shores, streamsides, in dune-slacks, marshes, water-meadows, flood pastures, bogs and in ditches and track ruts. It usually grows in oligotrophic or mesotrophic water over neutral to acid substrates. 0-930 m (Carnedd Llewelyn, Caerns.).
There is some evidence for a loss of R. flammula in S.E. England, but it remains frequent elsewhere. Subsp. flammula occurs throughout the British and Irish range of the species; the two rarer subspecies are mapped separately.
European Temperate element.
