The term "genus Allium" refers to a group of plants that includes onion, garlic, leeks, chives, shallots, and more. These plants are characterized by their edible bulbs or leaves and their pungent, aromatic flavors. Some common synonyms for the genus Allium include the onion family, alliums, and bulb vegetables. Other terms used to describe this group of plants include allicin-rich foods, as they contain high levels of an antioxidant compound called allicin. Additionally, some cultures refer to specific members of the Allium genus by their unique names, such as scallions (for green onions) or ramps (for wild leeks).
