Eryngium maritimum, the sea holly or sea eryngo, or sea eryngium, is a perennial species of flowering plant in the family Apiaceae and native to most European coastlines. It resembles a thistle in appearance because of its burr-shaped inflorescences. Despite its common name, it is not a true holly but an umbellifer.
It grows as an erect, spreading or scrambling shrubby herb, up to 1.5 metres tall, usually with a great many stems. Its leaves are dark green, stiff, with sharp spines at the end of each deep lobe: very much like those of holly (Ilex). Flowers are blue, purple or white, and occur in spikes terminal on the branches.
The genus name Eryngium was established by Linnaeus in 1753 where he mentioned eight species, including two from America (E. aquaticum, E. foetidum).Linnaeus, in Genera Plantarum (1754), cited his source of the name Eryngium as being from Joseph Tournefort’s Institutiones rei herbariae (1700).
