Eryngium foetidum is a tropical perennial herb in the family Apiaceae. Common names include culantro, recao, chadon beni, Mexican coriander, bhandhania, long coriander, sawtooth coriander, and ngò gai. It is native to Mexico, the Caribbean, and Central and South America, but is cultivated worldwide, mostly in the tropics as a perennial, but sometimes in temperate climates as an annual.
In the United States, the common name culantro sometimes causes confusion with cilantro, a common name for the leaves of Coriandrum sativum (also in Apiaceae but in a different genus), of which culantro is said to taste like a stronger version.
