A visitor from the seaside

There is lots of Danish Scurvygrass in flower at the moment, all along our roads. It's really a seaside plant, but is common on patches of bare ground on roadsides due to winter salting, often growing around the base of lamposts. The photos were taken near the traffic lights at the Waterside at Carr Mill Dam, but the plant can be found all along the East Lancs and Rainford bypass, and probably lots of other roads as well.
