Glasswort is a type of succulent plant that typically grows in coastal areas and salt marshes. It belongs to the family Amaranthaceae and is known for its fleshy, green stems that can turn red or purple in the presence of salt. The plant thrives in saline environments, making it an important species for stabilizing coastal ecosystems. Glasswort is often used in traditional cooking, particularly in seafood dishes, due to its salty flavor. It can be eaten raw in salads or cooked as a vegetable. Additionally, it has been used historically for its potential medicinal properties and as a source of soda ash in glass production.
