Sterling Onion is a hybrid, long-day onion variety that produces jumbo to colossal onions with a shiny, white exterior. This white onion variety is globe-shaped with a mildly pungent onion flavor. The plants are vigorous and produce strong, tall tops to protect the onion bulbs from sun damage as they mature. Sterling Onion has mid to long-term storage potential and is a great option for gardeners and small-scale farmers in long-day growing areas.
