Thomas Jefferson grew several types of onion at Monticello, including Madeira, Spanish, Tree, and White. The Red Wethersfield Onion is a 19th-century variety that derives its name from Wethersfield, Connecticut, where it reputably originated. It forms a large, flattened bulb 5" in diameter with purplish white, mildly pungent flesh.
Sow seeds indoors in mid to late winter, then harden off and transplant to moist but well-drained, fertile soil 4-6 weeks before the last frost date. Harvest when the foliage begins to turn yellow and fall over. Long-day type. Approximately 40-50 seeds per packet.
