Walla Walla

The classic large overwintering onion of the Pacific Northwest. A very large, juicy onion with a mild flavour. It can be planted in the spring or in August to overwinter. Spring-planted seeds result in bulbs that are not quite as mild as the overwintered ones, and spring-sown Walla Walla onions may not size up as well. Hardy to -23°C (-10°F).
These untreated seeds are not pelleted. For pelleted seeds, see ON566.
Matures in 150 days, spring sown - 300 days fall sown. (open pollinated seeds)
