Sweet onion

[3] In Europe, Oignon doux des Cévennes, Cipolla Rossa di Tropea Calabria and Cebolla Dulce de Fuentes are well known and tasty sweet onions.

The Cebolla Dulce de Fuentes is an open variety originally from Zaragoza province in northeast Spain, and traditionally grown by producers there.

Grown only in the Rio Grande Valley of South Texas, this large, prized onion was developed after ten years of extensive research and testing and a million dollars in cost.

As a result, Texas had a mild, very sweet onion with the nickname "Million Dollar Baby."

Christine Gregoire signed the "onion bill" in 2007 to make it the state's official vegetable.
