Garlic mustard (Alliaria petiolata) was introduced to North America as a culinary herb in the 1860s and it is considered an invasive species in much of North America. As of 2020 [update] it has been documented in most of the Eastern United States and Canada, with scattered populations in the west. [ 1 ]
Garlic mustard was introduced to North America by European settlers in the 1800s for culinary and medicinal purposes. [8] The species was recorded as being in Long Island in 1868. [ 9 ] It has since spread all over North America, apart from the far south of the US and some prairie states and Canadian provinces. [ 10 ]
This is a list of invasive species in North America.A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...

Garlic mustard was first introduced into the U.S. in 1868 in Long Island, New York, from Northern Europe and Asia. It was brought to the U.S. for erosional control as well as its herbal qualities.
Typically, an introduced species must survive at low population densities before it becomes invasive in a new location. [14] At low population densities, it can be difficult for the introduced species to reproduce and maintain itself in a new location, so a species might reach a location multiple times before it becomes established.
