Atriplex laciniata

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 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.
