Overview

Sea Sandwort forms spreading mats on the strandline and fore-dune, its fleshy oval leaves arranged in pairs along trailing stems. It's one of the first colonisers of bare sand, often growing with Sea Rocket but a little further up the beach. The small white flowers are pretty close-up. Like all strandline plants it can tolerate burial by sand and salt spray.
