Seriphidium maritimum
Ecology
An aromatic perennial herb occurring in the upper, drier parts of saltmarshes; also found on shingle, sea-cliffs, waste ground and walls close to the sea, by brackish dykes of drained estuarine marshes and on the banks of tidal rivers. Lowland.
Status
Trends
S. maritimum was lost from many sites in N. and W. Britain (and some elsewhere) before 1930, with further losses since. It is stable elsewhere and can be locally common, and is now better recorded, or perhaps increasing, in Ireland.
