A perennial herb of sea-cliffs, stone walls, stabilised shingle and saltmarshes. Inland, it grows on montane rock ledges, stony flushes and windswept moss-heaths, around old lead workings and other metalliferous mine wastes, and on riverside shingle. It also occurs inland beside salt-treated roads and as a garden escape. 0-1270 m (Ben Nevis, Westerness).
There has been little change in distribution since the 1962 Atlas, where it was mapped as `all records`, apart from its appearance from the 1980s on roadsides, mainly in S. England. Almost all British and Irish plants are referable to subsp. maritima; the rare subsp. elongata is mapped separately.
Circumpolar Wide-boreal element.
