Growing Information

About Walla Walla Onion
Walla Walla is a classic heirloom white onion prized for its outstanding sweetness, juiciness, and enormous size. Originating from the Pacific Northwest, it thrives in our coastal BC climate and develops its best flavour when overwintered. Sow seeds in mid-August and allow the plants to establish before winter—sugar content helps the plants survive frost. Harvest large, flavourful bulbs in spring for fresh use. Walla Walla can also be sown in early spring and harvested the same year, though overwintering yields larger, sweeter bulbs. This variety does not store well, so enjoy it fresh in salads, sandwiches, and savoury dishes.

Where Can You Grow Walla Walla Onion?
Best suited for Zones 3–9, Walla Walla onions prefer full sun, fertile soil, and steady moisture. Great for garden beds or rows with good drainage.

History and Historical Uses
Brought to the Pacific Northwest by a French soldier in the 1800s, this onion became regionally famous for its exceptionally mild and sweet flavour. It was named after the town of Walla Walla, Washington, and has since become a staple in home and market gardens.
