A variable shrub growing in a range of habitats. The prostrate var. argentea and var. repens are typically found on fixed dunes and especially dune-slacks, in maritime heaths and heathy grassland and on inland heaths and moorland. The erect var. fusca is found in fens. The species becomes more confined to moist or wet habitats in the south and east of its range. 0-855 m (Atholl, E. Perth).
The species has declined, especially inland in England, but since it was mapped in the 1962 Atlas as `all records` it is difficult to know when these losses occurred.
Eurosiberian Boreo-temperate element.
