Alliaria petiolata, commonly known as garlic mustard, is a biennial herbaceous plant in the mustard family. It produces heart-shaped, toothed leaves with a distinctive garlic-like aroma when crushed, along with small white flowers in spring. Native to Europe and parts of Asia, it has naturalized widely in North America, where it is considered invasive in many areas. Check local regulations before growing or distributing these seeds.
The green, toothed leaves release a garlic-like scent when crushed.
Produces clusters of four-petaled white flowers, generally in spring.
Typically develops leafy growth in its first year and flowers in its second year.
Can spread aggressively by seed and displace native vegetation in some regions.

Important information about identifying garlic mustard and its potential to spread.
Garlic mustard commonly has heart-shaped, toothed leaves with a garlic-like smell when crushed. Its small white flowers have four petals and typically appear in spring. Identification should be confirmed carefully because other plants may look similar.
Yes, it is considered invasive in many parts of North America, where it can spread through seed and displace native plants. Its status varies by location, so consult local invasive-species authorities before planting or distributing it.
Only consider cultivation where local rules permit it and environmental guidance supports it. Because garlic mustard can spread aggressively, avoid sowing it in regions where it is invasive or restricted, and never allow it to spread into natural areas.
