Walla Walla Onion is a well-known open-pollinated sweet onion variety prized for its large, mild-flavored bulbs and reliable performance in home gardens. It produces thick, glossy green tops and round bulbs that are notably sweet and crisp, making it a favorite for fresh eating and summer cooking. This variety is a long-day type that performs best when planted in regions with longer summer daylight hours. Whether grown in raised beds, containers, or traditional garden rows, Walla Walla Onion offers an rewarding harvest for gardeners of all experience levels.
Walla Walla Onions are excellent for fresh slicing, salads, grilling, and mild salsas where their sweetness shines without sharpness. They can also be used in soups, casseroles, and sauteed dishes.
