Allium cepa, known as the onion, is a bulbous vegetable that comes in various colors such as yellow, red, and white. These bulbs have layered skins and long, hollow green leaves that grow from the top. Onions are an essential ingredient in many dishes, adding both flavor and texture to soups, stews, and salads. They also have health benefits, providing anti-inflammatory and antioxidant properties while being rich in vitamins C, B6, and manganese.
Onions come in various types, including yellow, red, and white, each with its distinct flavor ranging from sweet to pungent. The bulb itself is layered, and its papery outer skin can be white, brown, or purple, depending on the variety. The plant grows long, hollow green leaves, which can also be used in cooking. These leaves sprout from the top of the bulb and can reach up to a foot in height. The bulb size and shape vary depending on the variety and growing conditions.

Grows in Home Gardens
Onions thrive in full sunlight, requiring at least six hours of direct light per day. They can be planted in various environments, from raised beds to containers, as long as the soil is loose and well-draining. Onions prefer rich, loamy soil that is high in organic matter for optimum growth. They do best in cool weather, making them ideal for planting in early spring or fall, depending on your region. Because onions need consistent moisture, it’s essential to water them regularly without allowing the soil to become waterlogged. If properly spaced and cared for, onions can flourish in most home gardens.
