Idaho Eastern Oregon Onion Committee
Idaho-E. Oregon Onion Committee/USA Onions
Idaho and Eastern Oregon is the only storage onion growing region in the United States governed by a Federal Marketing Order (#958). The onions are Federal-State inspected daily to assure they are in accordance with grade, size, pack and maturity requirements before they are shipped.
Growers in the sunny, fertile Snake River Valley of Idaho and Eastern Oregon produce more high-quality storage onions than any region in America. The combination of the valley's climate and soil creates favorable growing conditions for third and fourth generation farmers who harvest more than 21,000 carlots (40,000 lbs. per carlot) annually.
The growers in this region plant yellow, red, and white varieties of sweet Spanish seed. These onions are also known as "Spanish Onions" or "Spanish Sweets". The crop is planted in March and April. Harvest begins in August and continues into October. Yellow onions account for approximately 90% of the acreage. With state-of-the-art storage facilities, premium Idaho-E. Oregon Onions are available from August to March/April.
