About

Artemisia maritima is a European species of wormwood known as sea wormwood, and also formerly often by its synonym Seriphidium maritimum. It is native to the Atlantic coasts of northern Europe, from western and northern France, Ireland, the United Kingdom, Belgium, the Netherlands, Germany, Denmark, Sweden, Norway, the Baltic States, and northwestern Russia. In Great Britain, it is found as far north as Wigton on the west coast and Cruden Bay on the east coast, and in Ireland, on the east and west coasts between Dublin and Killough, and Tralee Bay to Galway; it also occurs on the Isle of Man.

There are two subspecies:

Where it grows

It occurs mostly on saline soils, being found on the drier parts of saltmarshes, brackish ditches, sea cliffs, and coastal shingle. As with many other saltmarsh plants, it has started to colonise inland along roadsides that are salted to melt winter ice and snow.
