Zinnia grandiflora is a species of flowering plant in the aster family known by the common names Rocky Mountains zinnia and plains zinnia.[2] It is native to the southwestern and south-central United States (Kansas, Oklahoma, Texas, Colorado, New Mexico, Arizona)[3] and northern Mexico (Chihuahua, Coahuila, Sonora, Tamaulipas, Nuevo León, Zacatecas).[2][4]

Zinnia grandiflora is a small flat-topped or rounded subshrub growing up to 22 centimeters (8.8 inches) tall with many slender, branching stems. The oppositely arranged leaves are linear and 1 to 3 centimeters (0.4-1.2 inches) long. The herbage is covered in short, rough hairs. The flower head has 3 to 6 bright yellow ray florets each between 1 and 2 centimeters (0.4-0.8 inches) in length. At the center is a cluster of several tubular disc florets. It grows on plains and foothills and other dry habitat.[2]


This plant is used by several Native American groups, including the Zuni and Navajo, for medicinal and ceremonial purposes.[5]

Among the Zuni people, this plant is applied in a poultice to bruises, cold infusion of blossoms used as an eyewash, and smoke from powdered plant inhaled in sweatbath for fever.[6]
