Crithmum is a monospecific genus of flowering plant in the carrot family Apiaceae, with the sole species Crithmum maritimum, known as rock samphire, sea fennel or samphire. The name "samphire" is also used for several other unrelated succulent halophyte species of coastal plant.
Sea fennel, or Rock samphire, is an edible wild plant. It is found on southern and western coasts of Britain and Ireland, on Mediterranean and western coasts of Europe and in the Canary Islands, North Africa and on the coast of the Black Sea.
Rock samphire or sea fennel has fleshy, divided aromatic leaves that Culpeper described as having a "pleasant, hot and spicy taste".
The stems, leaves and seed pods may be pickled in hot, salted, spiced vinegar, or the leaves used fresh in salads.
Sea fennel pickle in olive oil or vinegar is a traditional food of Italy (Marche region), Croatia (Dalmatia), and Montenegro (Bay of Kotor). It is known as Paccasassi del Conero and used as an antipasto, to accompany fish and meat dishes and to garnish pizza and sandwiches.
