Ecology

A rhizomatous perennial herb found in emergent stands on the edges of lakes and ponds, rivers and streams, in ditches, swamps, fens and bog pools, wet meadows, flush-bogs on hillsides, sea-cliff flushes, wet dune-slacks, and Alder and Salix carr. It usually grows in oligotrophic or mesotrophic, acidic waters, though it also occurs in nutrient-poor calcareous conditions. 0?1040 m (Creag Meagaidh, Westerness).
