What is it?

Garlic Mustard is on Michigan's Invasive Species watch list. It is a weed-like plant that's easily identified by the garlic-like smell that's produced when its leaves are crushed. Its leaves are triangular in shape and have sharp, jagged edges. Small, white flowers appear early in the summer.

Impacting Local Habitats

Garlic Mustard chokes out native under-story plants including tree seedlings. It releases toxins into the soil to prevent other plants from germinating in the area.
