Sea holly (Eryngium maritimum) belongs to the Apiaceae (the Carrot family). It is a perennial herb that is native to most European coastlines. This herb grows in sand-dunes and in sandy gravel on shorelines, and up to a height of 20-60 cm. The leaves are waxy, stiff and spiny, blue-green in color with white veins. The flowerheads are globular, metallic blue rather than mauve, and borne in April to September surrounded by collars of spiky bracts.
