Gardeners' Notes:

Positive Cyberpotato On Aug 24, 2012, Cyberpotato from Hermann, MO (Zone 6b) wrote:

Unless there are two different onions going by the name "Super Star" this is a Seminis hybrid. Same variety as "Sierra Blanca" according to Johnny's and several other sites.

Intermediate zone white sweet onion. Very Large. Widely adapted but ideally adapted to dry areas. Somewhat susceptible to Botrytis in high humidity areas.

Grew very well in central Missouri using irrigated plastic culture. 5 - 6 inch bulbs.

Neutral Farmerdill On Apr 30, 2004, Farmerdill from Augusta, GA (Zone 8a) wrote:

From Japan, a white, sweet Spanish type onion. A short-day early variety that matched 'Primavera' in maturity during UGA trial. (100 days.)
