- Biennial herb that grows to about 3 feet tall, but can be a few inches to several feet tall
- Plants are single-stemmed if uncut (mowed)
- Small, white 4-petal flowers appear in early spring and are in clusters at the top of the stem. In northern Illinois, garlic mustard is the only tall, white-flowered, four-petalled plant that blooms in May.
- First year the plants are low-growing rosettes with round, kidney-shaped leaves, scalloped on the edges (see photo taken in April 2014)
- Leaves without any fuzzy or hairy bits
- Upper leaves on mature plants are smaller, more coarsely toothed and less rounded (maybe even triangular)
- Plants often smell like garlic, especially when leaves are crushed (smell is gone by fall)
- Garlic mustard has a white slender taproot, with a characteristic crook or "s" shape at the top of the root, just below the base of the stem.
