Reviews
  • Open pollinated. 110 days. Until June or July from a fall planting. Heirloom.
  • Walla Walla Onion is the gourmet onion of the Pacific Northwest. Some say the world's best tasting onion,  large, fragrant and mild.
  • For years growers in Walla Walla, Washington have been planting this onion between August 15 and September 1, which then overwinters and withstands temperatures 10° below zero. Harvest begins in June and produce stands all around the north-west display banners saying Walla Walla Sweets Are In. 
  • We recommend this onion for fall or spring planting.
Planting Directions:  Direct sow in spring as early as the ground can be worked and soil temperature  is between 50˚ and 95˚. Plant seed ½” deep. Sow indoors 8 weeks before last frost in spring. Keep soil temperature 50˚ to 95° and consistently moist for optimum germination. Plant in loose, well drained soil that has been enriched with compost or a general purpose garden fertilizer. Plant seed in a trench and as the onions grow fill in the trench with soil as this is a very tall bunching type onion. When the plants are 2” high, thin 2” to 3” apart. The greens you thin can be used in cooking or salads. Water moderately on a regular schedule. Plant in late summer for an early crop the next spring or summer.
