    • Red Onions

    • The Bulb Onion, Allium cepa, also known as the “garden onion“, of the same genus (Allium) as the chive (A. schoenoprasum), garlic (A. sativum), leek (A. porrum), and shallot (A. ascalonium).
    • Above ground, the bulb onion shows only a single vertical shoot; the bulb grows underground, and is used for energy storage, leading to the possibility of confusion with a tuber, which it is not.
    • Bulb onions are the common round onions we are familiar from the grocery store as opposed to non-bulb onions like scallions or leeks.
    • Bulb onions are tasty and healthy foods that do not take up a lot of space, yet keep reasonably well after harvesting.
    • Bulb onions are easy to grow and are a great crop to plant in the vegetable garden.

    Description

          • Bulb onions are characterized by an edible bulb composed of food-storage leaves that are rich in sugar and a pungent oil, the source of its strong taste.
          • Among the hardiest and oldest garden-vegetable plants, onions bear a cluster of small, greenish white flowers on one or more leafless stalks.
          • The leaf base swells to form the underground mature edible onion.
          • Onions are pungent; because they contain a sulfur-rich volatile oil, peeling or slicing them can cause a person’s eyes to tear.
          • Onions vary in size, shape, colour, and pungency. Though low in standard nutrients, they are valued for their flavour.
