Long-Day Onions

Summer days are longer at higher latitudes than at lower latitudes, and onions bred to perform at high latitudes are known as long-day onions. Long-day onions grow best in the US and Canada north of a line drawn between San Francisco and Washington, DC, and receive their cue to start bulbing when day length reaches 14 to 16 hours.

Refer to our Full-Size Onion Comparison Chart to select the long-day onions best suited to your needs.
