The onion (Allium cepa L., from Latin cepa “onion”), also known as the bulb onion or common onion, is a vegetable that is the most widely cultivated species of the genus Allium. Its origin comes from southeast Asia, from regions of Afghanistan, Uzbekistan and Tajikistan. It is widely known for a thousand of years, because of its healing properties, its easy cultivation and long lifespan, when stored. Light, sandy soil, with good drainage helps onions to have good development and bigger bulbs. Their planting depends on their kind, for example if you wish to plant a spring onion, you can do it anytime of the year. If you wish to plant a dried onion, you can do it between March and April. In Greece you can find many varieties depending on their shape of the bulb, color, size and taste. There are sweet and chili onions, oblong or round, white, red or purple. There are a lot of local varieties of spring onions and regions that are widely known for their onions, such as the onions from Vatika, the water onions from Zakynthos, as also local varieties in Heraklion and Chania of Crete.
