AKA "Silver Ball" and "White Rocca." A long day onion for the northern states. This onion has a handsome globe-shaped bulb. It grows to a large size with pure white skin and flesh of mild flavor. Seedsman Thomas Griswold once wrote that this was the "best white onion for market," and Southport is still one of the best white keepers available today. This Connecticut heirloom was named after the town of Southport and grown along Connecticut's Mill River. Onions were exported by the millions from this agricultural epicenter also known as the "Onion Capital." The Civil War increased the demand all the more because pickled onions were used to keep scurvy at bay. May be used to produce scallions, requiring only about 65 days.
