Because onions are small and their tissues leave little or no trace, there is no conclusive opinion about the exact location and time of their birth. Many archaeologists, botanists and food historians believe onions originated in central Asia. Other research suggests that onions were first grown in Iran and West Pakistan.

It is presumed that our predecessors discovered and started eating wild onions very early – long before farming or even writing was invented. Very likely, this humble vegetable was a staple in the prehistoric diet.

Most researchers agree that the onion has been cultivated for 5000 years or more. Since onions grew wild in various regions, they were probably consumed for thousands of years and domesticated simultaneously all over the world. Onions may be one of the earliest cultivated crops because they were less perishable than other foods of the time, were transportable, were easy to grow and could be grown in a variety of soils and climates. In addition, the onion was useful for sustaining human life. Onions prevented thirst and could be dried and preserved for later consumption when food might be scarce.

While the place and time of the onion’s origin are still a mystery, there are many documents, from very early times, which describe its importance as a food and its use in art, medicine and mummification.


Colorado is centrally located making transportation much easier to ship east, west, north or south. With a number of major interstate highways easily accessible from all three onion producing areas in Colorado your next load of onions is a phone call away!

Colorado is comprised of three major growing areas. The first area is the Front Range from Denver to the Wyoming border. The Western Slope is the second production area from Grand Junction to Delta and Montrose. The third production area is in Southern Colorado, this area extends from Pueblo east to Grananda.
