Walla Walla Onion Plants (Heirloom, Long Day)

Walla Walla is the legendary sweet onion of the Pacific Northwest, tracing its roots to 1900 when French soldier Peter Pieri brought seeds from the Mediterranean island of Corsica to the Walla Walla Valley—where generations of careful selection by Italian immigrant farmers like the Arbini and Locati families transformed it into the ultra-mild, jumbo sensation we know today. This long-day variety thrives in cool northern summers, producing flattened golden bulbs with ultra-juicy, translucent white flesh that's famously sweet enough to eat raw like an apple, earning it the title of Washington's official state vegetable in 2007 after a spirited student-led campaign. Each bundle contains approximately 75 healthy, premium, non-GMO plants grown with natural and regenerative practices. Use fresh; not a storage onion.
