Salicornia europaea or glasswort is a halophytic annual dicot which grows in various zones of intertidal salt marshes. Salicornia europaea is highly edible, either cooked or raw. In England, it is one of several plants known as samphire (see also rock samphire). Samphire is usually cooked, either steamed or microwaved, and then coated in butter or olive oil.
