About

Atriplex laciniata, generally known as frosted orache, is a silvery-white sprawling plant that occurs on sandy beaches, mainly along the western coasts of Europe, and (much more sparsely) in the Mediterranean. It has been introduced to North America, probably with ballast on ships, but it remains very rare. It is a characteristic annual plant of strandline vegetation at the top of beaches and one of the earliest colonisers of bare sand.

Where it grows

Frosted orache is quite a rare plant, globally, being largely restricted to the Atlantic coasts of western Europe - mainly around Britain and Ireland, from northern Spain to Denmark and Sweden. In Norway it is mainly on some southern beaches, and there are small outlying populations on the Mediterranean coasts of Spain, France and Corsica.
