A perennial herb of lowland bogs, floating Sphagnum rafts in lowland basin mires, nutrient-poor mires in the mountains, and wet, acidic, occasionally sandy heaths. 0-1100 m (Ben Alder, Westerness).
The 1962 Atlas shows a decline in this species since 1930, especially in England. Since then, a few more sites in the lowlands have been lost to drainage, but many more have been discovered in the west, particularly in Wales and N. Ireland.
Circumpolar Boreal-montane element.
