Distribution: Forests and meadows from 5000 to 12000 feet. In Arizona, A. parvifolia is found in Coconino, Navajo, Apache, Gila, Yavapai, Graham, Cochise, and Pima counties. A. parvifolia is found in nearly all of the continental Western states: Colorado, Idaho, Montana, Nevada, New Mexico, Utah, Washington, and Wyoming, as well as Michigan, Minnesota, North Dakota, Okalahoma, South Dakota, and Texas (1). It is also found in Mexico (Chihuahua, Nuevo León) (2).
Antennaria parvifolia is poor forage and readily colonizes heavily grazed areas in the absence of competition. It is a good soil stabilizer and commonly colonizes burned areas. A tea from this plant is used for liver inflammation and hepatitis symptoms. A douche made from the leaves is used to treat vaginitis. The greens are used for food, medicine, and smoke. This plant was historically used for totem protection (4).
