Description
Onion 'Sweet Spanish Yellow' (Allium cepa), also known as Yellow Sweet Spanish, is a renowned open-pollinated heirloom long-day globe onion famous for its massive size, golden skin, and mild flavor. Developing large, globe-shaped bulbs that routinely reach 1 to 2 pounds, it features shiny, straw-yellow outer skins surrounding thick, crisp, white-to-pale-yellow interior rings. Carrying a mild, sweet taste with very little sulfur heat, Sweet Spanish Yellow is an ideal choice for fresh slicing on sandwiches, grilling, dicing into relishes, making onion rings, and short-to-medium cellar storage.
