Grown properly only in a small pocket of south Georgia, the Vidalia onion matures into unsurpassed sweetness in the spring. In one of nature's most delicious mysteries, the granex seed, which produces a hot onion elsewhere, grows into an onion one "can eat like an apple" in the fields around Vidalia and Glennville. The bill designating the Vidalia onion as the official state vegetable was enacted by the General Assembly in 1990.
