Walla Walla Onion is one of the sweetest onions you can grow, famous for its mild flavor and extra-large bulbs. This long-day variety produces crisp, juicy onions that are perfect for slicing onto burgers, salads, and sandwiches, or enjoying fresh without the sharp bite of many other onions. Walla Walla stores for a shorter time than storage onions, but its exceptional sweetness makes it a favorite for home gardeners.
