Crambe maritima

Crambe maritima (common name sea kale,[1] seakale or crambe[1]) is a species of halophytic flowering plant in the genus Crambe of the family Brassicaceae (also known as Cruciferae), that grows wild along the coasts of Europe, from the North Atlantic to the Black Sea.

The plant is related to the cabbage and was first cultivated as a vegetable in Britain around the turn of the 18th century. Blanched stems are eaten as a vegetable, and had become popular in the mid-19th century in Britain, in Victorian times.

Growing to 75 cm (30 in) tall by 60 cm (24 in) wide, it is a mound-forming, spreading perennial.[2] It has large fleshy glaucous collard-like leaves and abundant white flowers. The globular pods contain a single seed.
