Comments: Garlic mustard has a strong garlic odor and a distinct peppery taste. This flavor comes from an alkaloid called allicin which is also found in garlic. The odor and taste lessens as the year moves on. Native to Europe where it is not aggressive, it has become highly invasive in North America. The edibility of this plant has sparked "picking parties" whereupon groups pull the weed then create dishes to share with it (Eastman 2003).
