Garlic mustard is native to Europe. It was first brought to New York state in the 1800s, mostly likely for food or medicinal purposes. It has fully colonized the eastern and midwestern US.
This plant invades upland woodlands and floodplain forests, and frequently occurs along roadsides, trails, forested openings and waterways. It thrives under a wide range of light and soil conditions. Associated with calcareous soils, it does not tolerate high acidity.
Garlic mustard spreads by seeds. It is prevalent through the southern half of the state and continues to spread north. View garlic mustard distribution in Minnesota.
It is highly invasive and detrimental to forest understory health and biological diversity. Native understory plants have a hard time competing with invading garlic mustard populations. It can spread into high quality woodland habitats, not just into disturbed areas.
