An insectivorous rosette-forming perennial herb of damp acid heath and moorland, bogs and upland flushes, growing among Sphagnum or on bare acid peat. It can be an abundant colonist of ditch sides cut through wet, peaty ground. 0-670 m (Snowdonia, Caerns.) and reportedly to 700 m in the Scottish Highlands.
The overall distribution of D. rotundifolia has not changed since the 1962 Atlas. A decline in S.E. England was already apparent then and has continued in lowland areas because of habitat destruction.
Circumpolar Boreo-temperate element.
