Garlic Mustard

Alliaria petiolata

Garlic mustard is an invasive herbaceous plant native to Europe. It is found across a range of abiotic conditions and is often associated with high disturbance areas. Garlic mustard’s ability to rapidly establish dense patches and crowd out desirable native herbaceous (e.g. trillium, bloodroot, etc.) makes this non-native plant a threat to local biodiversity. Although first and second-year leaves from this biennial’s leaves may look different, they can both be distinguished from lookalikes by their pungent garlic odor when crushed.
