An erect annual of open, usually sandy or silty places near the sea, often forming dense stands along saltmarsh drift-lines, estuarine banks and sea-walls, and on waste ground around docks. It also grows in saline areas inland, and as a colonist by salt-treated roads. Lowland.
The coastal distribution of A. littoralis has remained largely unchanged since the 1962 Atlas, but from the early 1980s onwards it spread rapidly along inland roadsides, particularly in E. England.
Circumpolar Temperate element, with a disjunct distribution.
