Garlic mustard is an exotic invasive plant from Europe that invades woodland habitats in North America and impacts forest biodiversity. In some woodlands, dense stands of garlic mustard in the spring threaten showy spring blooming ephemerals like spring beauty, trilliums and trout lilies. Other research points toward potentially negative impacts on timber species and forest health. Many land managers consider it to be one of the most potentially harmful and difficult to control invasive plants in the region.
This site is intended to help you identify garlic mustard and learn about its biology, potential impacts and management. It is also the gateway for information on Michigan State University's garlic mustard research program.
