Ageratina paupercula, called the Santa Rita snakeroot, is a North American species of shrubs or perennial herbs in the sunflower family. It is found only in the states of Arizona, Sonora, Chihuahua, Durango, Nayarit, and Jalisco.[2][3][4]

The epithet paupercula is feminine of pauperculus, Latin for "poor." The "Santa Rita" part of the common name refers to the Santa Rita Mountains in southern Arizona, south of Tucson, where the species was initially discovered.[5][6]
