Fountain Grass (Pennisetum setaceum)
In 2020, Fountain Grass was listed as an Arizona Noxious Weed. This prohibits its sale or import into the state. Native to Africa and the Middle East, Fountain grass has been introduced to many parts of the world as an ornamental grass. Fountain Grass is expanding its range in Arizona and the Southwest.
Its rapid spread poses a significant threat to ecosystems, as it outcompetes native vegetation, provides fuel for wildfires, and negatively impacts wildlife habitat. Effective management of fountain grass involves a multifaceted approach, including prevention through public education and responsible recreation, early detection, manual removal, targeted herbicide application, and restoration efforts focused on reintroducing native vegetation and employing adaptive management strategies. Visit the USDA Weed Field Guide for the Southwest Website for comprehensive information on understanding, prevention, and the best management practices for managing fountain grass to protect the health of Southwestern forests and grasslands.
