"A Vidalia onion is a sweet onion of certain varieties, grown in a production area defined by law in Georgia and by the United States Code of Federal Regulations (CFR). The varieties include the hybrid yellow granex, varieties of granex parentage, or other similar varieties recommended by the Vidalia Onion Committee and approved by the U.S. Secretary of Agriculture.

The onions were first grown near Vidalia, Georgia, in the early 1930s. It is an unusually sweet variety of onion, due to the low amount of sulfur in the soil in which the onions are grown. Mose Coleman is considered the person who discovered the sweet Vidalia Onion variety in 1931.

Georgia's state legislature passed the "Vidalia Onion Act of 1986" which authorized a trademark for "Vidalia Onions" and limits the production area to Georgia or any subset as defined by the state's Commissioner of Agriculture." (Wikipedia)
