Garlic mustard is a herbaceous plant that is biennial. A basal rosette, or round arrangement of leaves close to the ground, forms the first year. These leaves are alternate and kidney-shaped with toothed margins. During their second growing season, the basal rosette produces 2 to 4 flower stalks that can reach a height of 3 feet (1m). The leaves of the flower stalks are alternate and heart-shaped to triangular with toothed margins. Flowers are small, white, and have 4 petals and are arranged at the tallest point on the flower stalk (Miller 2004). The blooming period occurs from April to May and the small brown to black seeds are dispersed in late summer. The seeds are contained in long, narrow capsules that can easily release up to 3,000 seeds per plant. Seeds are dispersed by humans, animals and water (Huebner et al. 2007).
