Garlic Mustard

Garlic mustard is an invasive species that is native to Europe.  Once established, it dominates the understory of North American forests and therefore reduces the biodiversity of these areas.


Garlic Mustard produces cyanide compounds which suppress mycorrhizal fungi that most plants, including native forest trees, require for optimum growth.


In the first year, plants appear as a rosette of green leaves close to the ground; these rosettes remain green through the winter and develop into mature flowering plants the following spring.  Plants are easily removed by pulling out by the root, or regular mowing.


Garlic mustard was originally cultivated in the US for its medicinal and food use.

The chopped leaves can be used for flavoring in salads and sauces such as pesto.
