Garlic Mustard (Alliaria petiolata) native to Europe and Asia, has become an invasive species within the U.S. These plants are members of the mustard family and taste as such with a strong, garlicky addition.
These plants are often found along roadsides or field edges. The tricky part is to find it far enough away from the road to safely harvest from a health perspective. We like to stay 30ft away from the road to minimize exhaust and drainage contamination. We found some little pockets and harvested a good quantity of this plant. Pulling them out by the roots is best from an invasive management perspective.
The tender stalks make a great pesto and the leaves (stronger flavor) are good additions to soups.
