Porophyllum ruderale, also known as papalo, Bolivian coriander, quirquia, or yerba porosa, is an annual herbaceous plant that is native to the warm temperate zone of southern North America and south through the tropical Americas to Bolivia and Peru. It is commonly found in very freely draining soils, often in semi-arid regions where it grows after rains. The plant is known for its distinctive leaves, which can be used for seasoning food. The taste of Porophyllum ruderale leaves has been described as "somewhere between arugula, cilantro, and rue". It is commonly grown in Mexico and South America for use in salsas and other dishes. When fully grown, the plant can reach a height of about 150 cm (5 ft) and a diameter of 90 cm (3 ft). Porophyllum ruderale is relatively easy to grow from seed in a well-drained soil, which should be allowed to dry between watering. It is an herbaceous annual plant that thrives in the seasonally dry tropical biome. In its native lands, Porophyllum ruderale has traditional uses as both medicine and food. However, it is important to note that Porophyllum ruderale is considered an invasive forb in Hawaii and is quickly establishing itself there. Overall, Porophyllum ruderale is a versatile plant with culinary and medicinal uses, known for its unique flavor and adaptability to various growing conditions.
