Hordeum marinum
Also called Sea Barley, Mediterranean Barley, Geniculate Barley, Sea Barley Grass, Salt Barley Grass, Salt Barley
Seaside barley is a small annual grass that grows on bare, salty or disturbed ground near coasts and inland salt flats. It is not typically grown as a garden plant, and its key requirement is open, moist, saline or disturbed soil in full sun.
Hordeum marinum, commonly known as sea barley or (subspecies gussoneanum) Mediterranean barley, is a species of flowering plant in the grass family Poaceae that grows on bare ground on the shores of Europe and North Africa. It is also found in inland salt flats such as the Pannonian grasslands of Hungary, and it is widely established outside its range in temperate regions of both the north and south hemispheres. It is an annual, producing copious seed when habitat conditions are right, but not persisting in competition with other species. Although it is a relative of an important crop species, it has no uses itself.
Sea barley is native throughout Europe, North Africa and as far east as central Asia. It is also established as an introduction in North and South America, South Africa, Australia and Japan. Although it is primarily a coastal plant, it is by no means restricted to seaside areas.
