Because Vidalia® onions are sweetly unique, farmers united to seek legal protection for their crop and its name. Federal Marketing Order No. 955 was established in 1989, to stipulate where the crop can be grown and help with research and promotion of Vidalia onions. The Vidalia Onion Committee administers FMO No. 955 and authorizes production research, marketing research and development and marketing promotion programs. This federal program along with Georgia state laws that protect the Vidalia trademark have provided a legal framework for the industry. So, you can try to grow a sweet onion elsewhere, but you cannot call it a “Vidalia,” unless it is from Georgia!
