Inula britannica L. (ITIS)
British yellowhead, British elecampane, meadow fleabane
Europe and Asia (Oregon Fish & Wildlife 2005)
Typically found in U.S. nurseries in hosta plants imported from the Netherlands (Lehtonen and Schall 2009)
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)
