Cosmos caudatus is an annual plant in Cosmos genus, bearing purple, pink, or white ray florets. It is native to Latin America (from Rio Grande do Sul in southern Brazil to Tamaulipas in northeastern Mexico), and the West Indies, though naturalized in tropical parts of Asia, Africa, and Australia.
Cosmos caudatus is edible and its common names include ulam raja, literally meaning "the King's salad". It was brought by the Spaniards from Latin America, via the Philippines, to the rest of Southeast Asia. Ulam, a Malay word used to describe a preparation that combines food, medicine and beauty is the widely popular Malay herbal salad. As a Malaysian delight, it is served throughout the country from major hotels for tourists to buffet lunches or dinners for the locals.
