'Newburg' is a wonderful open-pollinated onion with yellow-white flesh and copper skin. Many people assume it is an old heirloom (and it is sometimes sold as such now), but it is actually a de-hybridized jewel from Dr. Alan "Mushroom" Kapuler. He began with a Vilmorin hybrid from France and spent many years transforming it into a productive, consistent, vigorous open-pollinated variety. It was bred under and for organic conditions, and in trials it regularly performs better than commercial hybrids in organic systems. If you need a solid work-horse onion for your farm or garden, this is it. Our seed was grown by Cass McKinnon and Clint Freund in Wisconsin.
GROWING TIPS: Definitely best to transplant healthy onion starts in early spring. Start them in indoors or in greenhouse. We typically put 3-4 seeds per cell in 50-cell or 72-cell trays, transplanting out the entire cell with 3-4 onion starts in it together. Plant out individual cells every foot.
