Garlic Mustard

Printer-friendly version

Garlic mustard (Alliaria petiolata) is a highly invasive plant that aggressively outcompetes native forest plant species.

Long-term research at the Forest has determined how this exotic plant invades so rapidly and successfully. Garlic mustard exudes phytochemicals in the soil, which disrupt the important relationship between native plant roots and beneficial soil fungi, impeding native plants' ability to thrive.
