Garlic mustard

(Complete Item Description)

Abstract:: The garlic mustard plant was introduced as an herb to the United States. The problem with the plant is that it grows quickly, its seeds are viable for several years after production, and the insects and fungi that normally feed on the garlic mustard plant are not located in the U.S. Also, deer do not feed on these plants, so they tend to spread well in forested areas. Garlic mustard plants feed on fungi that are essential to the growth and life cycles of some trees.
