Walla Walla Sweet Onions have been produced as a specialty vegetable crop since 1900.
“Walla Walla” is a Native American word meaning “many waters.” The area has an abundance of trees and a moderate climate, with an average temperature range of 27 to 91 Degrees. The hardy Walla Walla Sweet Onions survive the nearly 18 inches of precipitation each year.
Aproximately 30 growers cultivate the Sweets on about 1,000 acres with an average yield of 650 50-pound units per acre.
Harvest takes place June through August where the Sweets are marketed as fresh produce to be used by the consumer within a short time of purchase.
The mildness of the Walla Walla Sweet Onion is not due to sugar, but to low sulfur content, which is half that of an ordinary onion. Less sulfur means less “bite” and no tears. The Sweets are widely known for their large size, weighing up to 2lbs. and measuring up to 5 inches in diameter. Separate the Sweets from each other in a cool, ventilated location and enjoy them fresh, or chop and store in the freezer for year-round pleasure.
Walla Walla Onion growers united in 1995 to form Federal Marketing Order No. 956 to protect their popular industry.
Violators can be prosecuted under federal law. A 10-member committee of growers and shippers administers the Marketing Order, which includes the authority for promotions and research projects. The program is funded with assessments on shipments of the product.
