Viola spp.
Similar to Alliaria petiolata (Bieb.) Cavara & Grande
Garlic mustard is distinguished from other woodland herb species by its characteristic garlic odor. As the odor gradually dissipates by autumn, first-year rosettes may be mistaken for violets (Viola spp.) or immature white avens (Geum canadense). Garlic mustard can be distinguished by its slender white taproot with a crook or "S" shape just below the base of the stem.
