Garlic mustard is an herbaceous plant often found in dense stands in the understory of forests. Garlic mustard is a biennial plant, taking two years to complete its life cycle. First year garlic mustard plants are small inconspicuous rosettes of small heart-shaped leaves close to the ground that remain green all winter. Second season garlic mustards are flowering plants that reach heights of 1-3 feet. One or two flowering stalks are common. The leaves on second year garlic mustards are coarsely toothed triangles. A strong garlic odor is given off when the leaves are crushed. Flowers are small with four white petals. The seed of garlic mustard come in long thin pods that are often abundant on the plant in late summer
