sea-rocket
Cakile maritima
Family: Brassicaceae.
Type: Annual herbaceous plant.
Leaves: Succulent, highly dissected leaves.
Twig: Growth form is sprawling and prostrate, typical of beach scrub.
Fruit & Flower: The name sea-rocket comes from the shape of the fruits, which look like little rocket ships. Its flower is typical of the mustard family.
Miscellaneous: Sea-rocket is non-native. It occurs far out into disturbed beach areas; it is the most primary of the primary dune plants, beginning colonization of open dunes and facilitating entry by other species. The native Cakile is very rare; this non-native species has replaced it ecologically.
