AAS Vegetable Award Winner
'Super Star' is an improved white sweet onion recommended for all spring gardens in North America because it is day length neutral. Most onions require long days (over 12 hours of sunlight) or short days to bulb. 'Super Star' does not have this requirement so it is widely adaptable. If seed is sown and transplanted early, 'Super Star' onions can weigh one pound or more, when mature in about 100 days. Resistant to pink root, 'Super Star' onions are exceptional when eaten raw, in salads or sandwiches. 'Super Star' is milder, sweeter and larger than 'White Sweet Spanish', the closest comparison.
