Eryngium pandanifolium, commonly known as the Giant Sea Holly, is native to southern and central South America. In its native habitat it is found in wet locations. It has become naturalised in south west Europe. Eryngium pandanifolium is synonymous with Eryngium decaisneanum.

The etymological root of the binomial name Eryngium is derived from the Greek hruggion, a name given by Theophrastus for ”a spiny leaved plant’. Pandanifolium is derive from Pandan (another plant) and folium meaning ‘leaf’, in reference to the similarity if its leaves to those of the Pandan.
