Walla Walla Sweet Onion

Heirloom. The pride of Washington state, this globe-shaped onion is exceptionally mild and makes jumbo- to colossal-sized bulbs with light brown skin and pretty white flesh. Sweetest of all the long-day varieties, it is the only long-day that comes close to matching the sweetness of Georgia Sweet. Exceptionally mild flavor. Will keep for a month. Delicious for fresh slices on sandwiches. Developed in the late 1800s, it still earns a place on the table.
