A tuberous perennial herb of calcareous marshes, fens, damp meadows, roadsides and dune-slacks, and also less acidic bogs and wet heathland. It avoids areas that are inundated for long periods, and is rarely found in drier sites such as chalk downland. It also colonises artificial habitats such as quarries and industrial waste ground. Lowland.
This species is much better recorded now than in the 1962 Atlas, especially in the English Midlands. Although there have been local losses to drainage and habitat destruction, mostly since 1930, it is still frequent in suitable habitats in many areas and may have increased in man-made habitats.
Oceanic Temperate element.
