Glasswort is a type of succulent plant that typically grows in coastal areas and salt marshes. It belongs to the genus Salicornia and is known for its fleshy, green stems that can turn red or purple in the fall. Glasswort thrives in saline environments, making it well-adapted to survive in areas where other plants may struggle. This plant has been used historically for various purposes, including as a food source and for making soda ash, which is used in glass production. Glasswort is also valued for its role in coastal ecosystems, helping to stabilize soil and provide habitat for wildlife.
