Porophyllum ruderale is a herbaceous annual plant whose leaves can be used for seasoning food. The taste has been described as "somewhere between arugula, cilantro and rue." The plant is commonly grown in Mexico and South America for use in salsas. When fully grown, this plant grows to about 5 feet in height and 3 feet in diameter.
Thanks to its tolerance for heat, this garden green is sometimes called "summer cilantro." Bolivian coriander is another name, although it’s not at all related to that herb. No, this plant -- papalo (Porophyllum ruderale) -- is actually part of the daisy family and originated in South America, predating the arrival of Asian coriander by thousands of years.
