This is the classic large overwintering onion of the Pacific Northwest. A very large, juicy onion with a mild sweet flavour. It can be planted in the spring if given a really early start indoors, or in August to overwinter. Spring planted Walla Walla sweet onion seeds result in bulbs that are not quite as mild as the overwintered ones and may not size up as well. Plants can also be harvested as a delicious, sweet bunching onion.This variety is hardy to -23°C (-10°F). It is most definitely a long day onion, suitable for planting between the 35th and 55th parallels. It might not have good storage ability, but it makes beautiful, caramelized onions!
Matures in 125 days, spring sown - 300 days fall sown. (Open-pollinated seeds)
