Super Star is a mid-day or day length neutral white onion, which means that it can be grown from seed anywhere in North America. It's 20 days earlier to mature than other White Sweet Spanish types with no sacrifice in bulb size. The globe-shaped bulbs are attractive, have a mild, sweet flavor and retain their skins well. Super Star keeps well for a mild white onion, but like other whites, it’s not recommended for long-term storage.

Daylength: Intermediate Day (requires 12-14 hours of daylength to begin to bulb)

Plants: 50-60 transplants/count
