Oignon

<em>Allium cepa</em> is a biennial or perennial bulbous herb in the family Amaryllidaceae, cultivated globally as one of the most widely used culinary vegetables. Its exact wild origin remains debated, though it is thought to originate from Central Asia. Today, the species is grown across Africa, Asia, Europe, North America, South America, and Oceania, adapting to diverse agricultural climates and soil types. Common onion typically grows in grasslands, agricultural fields, wetlands, and cultivated habitats. The plant forms underground bulbs that store nutrients and are harvested for food. It produces distinctive hollow, cylindrical leaves and globular flower heads. Onion is valued for its sulfur-containing compounds, which contribute to its characteristic pungent aroma and flavor, as well as its antimicrobial and antioxidant properties. Its conservation status has not been formally evaluated by the IUCN due to its extensive cultivation and absence of wild population concern. Biological traits including average lifespan, length, weight, and dietary ecology remain poorly documented in standardized wildlife databases appropriate for a cultivated crop species. <em>Allium cepa</em> is among the most economically significant vegetables worldwide, grown in over 175 countries.
