Some leaves are shiny green, with the bluntest of teeth.


Not to be confused with : Sea Radish [a plant with similar name which also grows near the sea and also has four petals but they are usually yellow]. Nor with Wild Radish or Garden Radish.

Some similarities to : Cuckoo Flower in that the petals number four and are lilac in colour, but Cuckooflower doesn't grow in the saline conditions present so close to the sea.

Slight resemblance to : Sea Kale which also grows on the beach and has four (white) petals.

All the above belong to the same Cabbage (Brassicaceae) Family.

Sea Rocket is the only plant with lilac or mauve coloured petals which also grows near the sea. It may have lilac, whitish or pinkish petals. It grows mainly just on and above the drift line, on sand rather than on shingle.

The Genus Cakile has but one member in the UK, this one.

Occurs near the sea just above the drift line, usually on sand, but sometimes on shingle. The leaves are glaucous and look semi-succulent.
