The onion is the most widely cultivated species of the genus Allium, grown for its bulb and closely related to garlic, scallion, leek and chives. Its ancestral wild form is not known, and the source records no confirmed region or date of first domestication, a genuine open question rather than a settled fact. Onions are eaten raw or cooked worldwide and used in pickles and chutneys.
