''Eryngium'' is a genus of flowering plants in the family Apiaceae. There are about 250 species.〔Wang, P., et al. (2012). (Phytochemical constituents and pharmacological activities of ''Eryngium'' L. (Apiaceae). ) ''Pharmaceutical Crops'' 3 99-120.〕 The genus has a cosmopolitan distribution, with the center of diversity in South America.〔 Common names include eryngo and sea holly (though the genus is not related to the true hollies, ''Ilex''). These are annual and perennial herbs with hairless and usually spiny leaves. The dome-shaped umbels of steely blue or white flowers have whorls of spiny basal bracts. Some species are native to rocky and coastal areas, but the majority are grassland plants. ==Uses== Species are grown as ornamental plants in gardens. Numerous hybrids have been selected for garden use, of which ''E.'' × ''oliverianum''〔(''Eryngium'' × ''oliverianum''. ) Royal Horticultural Society.〕 and ''E.'' × ''tripartitum''〔(''Eryngium'' × ''tripartitum''. ) Royal Horticultural Society.〕 have gained the Royal Horticultural Society's Award of Garden Merit. Many species of ''Eryngium'' have been used as food and medicine. ''Eryngium campestre'' is used as a folk medicine in Turkey. ''Eryngium creticum'' is a herbal remedy for scorpion stings in Jordan. ''Eryngium elegans'' is used in Argentina and ''Eryngium foetidum'' in Latin America and South-East Asia. Native American peoples used many species for varied purposes. Cultures worldwide have used ''Eryngium'' extracts as anti-inflammatory agents. ''Eryngium'' yields an essential oil and contains many kinds of terpenoids, saponins, flavonoids, coumarins, and steroids.〔 The roots have been used as vegetables or sweetmeats. Young shoots and leaves are sometimes used as vegetables like asparagus. ''E. foetidum'' is used in parts of the Americas and Asia as a culinary herb. It is similar to coriander or cilantro, and is sometimes mistaken for it. It may be called spiny coriander or culantro.〔Ramcharan, C. 1999.
