Ailsa Craig Exhibition Onion is a long-day British heirloom from 1887. It forms large snow-white bulbs with single centers, vigorous tops, and very sweet flavor for raw slicing.
Sow 1/4 inch deep indoors 8-10 weeks before last frost at 60-75F. Sprouts in 5-10 days; transplant mid to late spring 2-6 inches apart when pencil-thick.
