Packera franciscana
Also called San Francisco Peaks Groundsel
Packera franciscana (syn. Senecio franciscanus) is a rare species of flowering plant in the aster family known by the common name San Francisco Peaks groundsel, or San Francisco Peaks ragwort. It is endemic to Arizona in the United States, where it is known only from the San Francisco Peaks in Coconino County. It is threatened by recreational activities in its habitat. It is a federally listed threatened species of the United States.
Packera franciscana grows on two of Arizona's San Francisco Peaks, Humphreys Peak and Agassiz Peak, and the saddle between them. These are the two tallest mountain peaks in Arizona. It grows in alpine tundra habitat in the volcanic talus of the mountain slopes, an area with little vegetation located above the tree line. This is the only alpine zone in Arizona. The elevation is between 3200 and 3800 meters, with most of the plants occurring between 3525 and 3605 meters.
