Walla Walla Sweet Onion, Heirloom Seeds

Walla Walla — The Sweet Heirloom Onion You Can Eat Like an Apple

Walla Walla is one of the most celebrated sweet onions in American gardening — and for good reason. Brought from France in the early 1900s, this exceptional heirloom produces extra-large white onions with light brown skin, with bulbs reaching up to 4 inches across. The flavor is so mild and sweet that Walla Walla is famous for being eaten raw, straight from the garden, like an apple. A day-neutral variety, it grows almost anywhere in the country regardless of day length — making it one of the most versatile onions available. Cold-hardy and reliable, it matures in 80–85 days from transplant.

Note: Walla Walla is a short keeper — best enjoyed fresh rather than stored long-term.

Why Grow Walla Walla?

• Sweet enough to eat like an apple — exceptionally mild, no harsh bite
• Extra-large 4-inch bulbs — impressive size with light brown skin
• Day-neutral variety — grows almost anywhere in the U.S., regardless of day length

Growing Notes

Start indoors 10–12 weeks before last frost. Transplant outdoors when seedlings are pencil-thick, spacing plants 4–6 inches apart in full sun with fertile, well-draining soil. Water consistently. Day-neutral — no need to match latitude or day length. Harvest when the tops begin to fall over and dry. Cure in a warm, dry location for 2–3 weeks. Best used fresh — not a long-term storage onion.
