VARIETIES TO PRODUCE BULBS IN THE SAN DIEGO AREA
Short Day (in San Diego plant seed in October or transplants in mid-November)
Granex - This is the Vidalia onion grown in Georgia and the Maui onion grown in Hawaii. The bulb has a thick, flat shape and mild, sweet flavor with short to medium storage. Granex hybrid 33 has a light, straw colored skin and mild, sweet flavor.

Grano - This onion is grown in Texas and other southern states. It is similar to Granex but the bulb is globe or top shaped. It has a sweet, mild flavor with short to medium storage. Texas Grano 502 is bolt resistant.

Red Burgundy - This onion produces a large, flattened globe 3-4” in diameter. It has a mild, sweet flavor but not as mild as Grano, Granex or Walla Walla.

Intermediate Day (in San Diego plant seed in February)
White Sweet Spanish - This onion produces a globe shaped white bulb. It has a mild flavor and medium storage life.

Italian Red Torpedo - This onion produces a long, torpedo shaped bulb with a purple red skin. It has a mild flavor but stores poorly.

Long Day (most varieties do not produce good bulbs in the San Diego area)
Walla Walla Sweet - This onion is grown in Washington State and seed may have been brought from Corsica, which is at the same latitude. Although this is a long day variety it grew well in my garden in El Cajon in 1985-86. I acquired seed harvested in May from a gardener and planted it in November. The bulbs had a mild flavor but were not as sweet as Grano or Granex.
