Distribution
Its habitat ranges from Georgia north to Ontario and from the Atlantic to Wisconsin. It is found in moist woodlands usually in edge habitats and blooms from April to June. A member of the mustard family, it is typified by a four petal flower which blooms in a cluster on a single stalk above a single pair of toothed stem leaves each divided into three broad leaflets. After flowering, narrow seedpods appear just below the flower cluster. It grows approximately 30 cm tall.
Habitat
The West Virginia white butterfly lays its eggs on this plant as well as ''C. laciniata''. The larvae also feed on this plant. As with ''Pieris oleracea'', ''Pieris virginiensis'' mistakes garlic mustard for its host plants, making eradication of it important for their continued survival. Garlic mustard also competes with the plants for space and nutrients.References:
