Question

where does onion grow??​

Answer 1

Answer:

Onions are a cool-weather crop and can be grown in USDA zones 3 to 9. Hot temperatures or other stressful conditions cause them to "bolt", meaning that a flower stem begins to grow. Onions may be grown from seeds or from partially grown bulbs called "sets".

Answer 2

Answer:

Many archaeologists, botanists, and food historians believe onions originated in central Asia. Other research suggests onions were first grown in Iran and West Pakistan. It is presumed our predecessors discovered and started eating wild onions very early – long before farming or even writing was invented.
