Dalmatian Toadflax (Linaria dalmatica) is native to Southeastern Europe and Western Asia and has become an invasive species in North America.
Dalmatian Toadflax is considered problematic due to its aggressive growth, prolific seed production, and ability to form dense stands, outcompeting native vegetation and disrupting ecosystems. Effective management involves a multi-faceted approach, including prevention, early detection, and control strategies. Control methods may include manual removal, mowing, targeted herbicide application, and the use of biological controls, such as herbivorous insects that feed on the plant. Integrated pest management practices are often recommended to address the invasive nature of Dalmatian Toadflax.
