Here are some interesting facts about this chameleon-like vegetable, onion!
What is Onion?
Allium cepa L.
Onions are members of the Allium genus of flowering plants that also includes garlic, leeks, and chives.
Onions like cooler temperatures and depending on the season, the flavor can be varied.
For example, during spring and summer, onions have more water content and are easily bruised, leading to shorter storage life. The flavor of these onions is sweet and mild.
However, during fall and winter, onions have less water content, leading to longer storage life. The flavor of these onions has a more pungent taste.
Types of Onions
The most popular and everyday onion.
Nearly 90 percent of the U.S. onion crop is yellow onions.
Yellow onions are suitable for any kind of cooking use.
Also, yellow onions have a longer storage life than other onion types.
As the name indicates, sweet onions are larger, lighter in color, and sweeter than yellow onions.
This onion is the best type of onion for caramelizing and making onion rings.

Often only available seasonally.
Although we call red onions, the skin color of these onions is closer to purple or magenta color.
Red onions are sharper yet milder than yellow onions and often eaten raw.
Because of its beautiful magenta color, it's a perfect addition to salads or other dishes to enhance the color contrast.
White onions have a softer and milder flavor than red and yellow onions, and they are great for salad.

Also known as spring onions, green onions are seasonal.
Green onions are immature onions that have not yet formed a bulb.
The entire plant is used, mostly the green part for garnish and the white part for grilling and sautéing.
Leeks are a member of the onion family.
Leeks look like green onions but they’re a lot larger yet milder in flavor.
History of Onion

Although their exact origin is a mystery, many botanists and archaeologists believe that onions originated in central Asia.
Early documents tell us that onions were important not only as a food but for medication, art, and mummification.
Because of the onions' unique shape with many layers, onions in Ancient Egypt symbolized eternity, so they were buried with pharaohs. Onions have frequently been found in other body cavities of mummies.
Early sixth century, the famous medical treatise Charaka-Sanhita celebrated the onion as medicine - a diuretic good for digestion, the heart, the eyes, and the joints.
