Walla Walla Onion - The World's Best-tasting Onion

Light brown skin, white flesh with a very mild and sweet flavor. A very cold hardy northern, long day onion that rivals the Vidalia onion. Hardy to -10ºF. This sweet onion was developed over several generations through the process of carefully hand selecting onions from each year’s crop, ensuring exceptional sweetness, jumbo size, and round shape of this traditional Washington sweet onion.

Seeds were brought back from Corsica, Italy to the Walla Walla Valley in Washington State around 1900. Sweet, mild, juicy and delicious as a raw salad onion or anyway you use it!


The onion exists only in cultivation and is thought to be a cultigen derived from wild species in the Middle East. It has a recorded history dating back to at least 3000 BC. They are now found worldwide and almost every culture incorporates them into their cuisine. 


Onions have an exceptionally wide range of culinary uses. They are eaten fresh or as an ingredient in salads, soups, sauces, stews, curries or processed in pickles and chutneys. The main attraction is the distinctive savory flavor which is due to a complex mixture of sulphur compounds. 

Growing Tip

Onion bulb development and size is dependent on day length.
