Species not Established in the U.S.

The following species of concern represent examples of why we must increase our efforts in early detection and rapid response and prevention of new introductions. See Manager's Tool Kit - Early Detection and Rapid Response: Species not Established in the U.S. for general resources and other species information.

This information is provided as an educational tool and is not inclusive of all invasive plant species not yet established in the U.S.

British yellowhead - Invasive.org

Scientific name: Inula britannica L. (ITIS)

Common name: British yellowhead, British elecampane, meadow fleabane

Native To: Europe and Asia (Oregon Fish & Wildlife 2005)

Date of U.S. Introduction: 1915 in New York; 1990 in Michigan (Morton and Hansen 2002); 2002 in Oregon (Oregon Fish & Wildlife 2005)

Means of Introduction: Typically found in U.S. nurseries in hosta plants imported from the Netherlands (Morton and Hansen 2002)

Impact: Negatively impacts the cultivation of hostas. Roots of Inula britannica look very similar to hosta roots and may become intertwined with them, making it difficult to detect and control. (Lehtonen and Schall 2009)
