Eryngium maritimum
Also called Seaside eryngo, Eryngo, Maritime Eryngo
Sea-holly is a bluish-grey, spiny, drought-tolerant perennial of coastal sand and shingle in Europe and the Mediterranean, with thistle-like blue-white flower heads. It is not a true holly but a member of the carrot family, and it needs sun, sharp drainage and little water.
Eryngium maritimum, also called the sea holly, sea eryngo, or sea eryngium, is a perennial species of flowering plant in the carrot family Apiaceae, native to the coasts of most of Europe and the Mediterranean. Its prickly holly-like leaves and compact flower heads give it the appearance of a thistle. Despite its common name, it is not a holly but an umbellifer.
The species is found along the coasts of most of Europe and the Mediterranean.
