This onion variety are less acidic and sweeter tasting than typical onions...and best eaten fresh! Originally found in Corsica and brought to the USA, Walla Walla was named after Walla Walla County and translates to 'many waters' by the Native American Plateau tribes.

As biennials, fall-sown Organic onions can overwinter and will grow large pale-yellow to white bulbs by next spring harvest, as soon as their tops completely dry and fall over. Packed with vitamins and are known to help lower blood pressure. Cool hardy vegetable. Matures 90-110 days.
