Genus Alliaria is a type of plant that belongs to the Brassicaceae family, also known as the mustard family. The Genus Alliaria is commonly referred to as garlic mustard or jack-by-the-hedge. Garlic mustard is a biennial weed that is native to Europe and was introduced to North America in the late 1800s. It has several synonyms, including Alliaria officinalis, Erysimum alliaria, and Sisymbrium alliaria. It is known for its distinctive garlic and mustard flavor and is often used in salads and as a seasoning. Garlic mustard is considered an invasive species and can outcompete native plants, leading to biological diversity loss.
