Sea purslane (Atriplex portulacoides, formerly Halimione portulacoides) is a low, silvery grey-green salt-marsh shrublet whose small, plump, oval leaves are foraged and eaten as a coastal leafy green. Snapping-crisp and juicy, they taste cleanly saline with a fresh, mineral, slightly nutty green note — milder and meatier than samphire — and are eaten raw, blanched or steamed as a seasoning-vegetable alongside fish and shellfish.
