The genus Alium contains the widely cultivated food crop known commonly as onion. As well as a wide range of the ornamental onions grown for summer displays. Onions are an easy to grow vegetable crop in the colder seasons because of their hardiness. They can also be grown in any soil type as long as it is well-draining and they receive a lot of sun. These are great vegetables for beginner gardeners as they do not require a lot of maintenance. Onions are most frequently a biennial or a perennial plants but they usually treated as an annual and harvested in its first growing season for the swollen, edible onion bulb. Onion plants produce chemicals called volatiles which repel harmful insects from other plants and can be used to create a natural insecticide spray when paired with cayenne pepper/red pepper and garlic.
