An annual of maritime rock crevices, cliff-tops, stabilised shingle, dune-slacks and disturbed areas in upper saltmarsh on sandy substrates; also on walls and tracks, in pavements and on sandy roadsides near the sea. A form of it, described as var. alpina, has been recorded at 1210 m on Ben Nevis (Westerness), though the identity of such plants requires confirmation.
There has been little significant change in the distribution of this species since the 1962 Atlas, although it appears to have declined or has possibly been overlooked recently in N.W. Scotland. It has recently been recorded from inland squares beside salt-treated roads.
European Southern-temperate element.
