Arenaria peploides, commonly known as sea sandwort, is a type of plant that is native to coastal regions. Some synonyms for this species include Honckenya peploides and Sabulina peploides. Despite the different names, they all refer to the same plant with small, fleshy leaves and white or pink flowers. Sea sandwort is often used in land reclamation projects due to its ability to stabilize sand dunes and prevent erosion. It is also an important food source for grazing animals such as sheep and rabbits. With its adaptability to saltwater environments and sandy soils, sea sandwort is a valuable asset to coastal ecosystems.
