Skip to product information
A classic long-day variety known for its large, globe-shaped bulbs and mild, sweet flavor, Sweet White Spanish is a garden favorite for fresh eating and summer harvests. The white flesh is crisp and juicy, perfect for slicing into salads, sandwiches, and salsas, with just enough bite to add flavor without overwhelming.
These onions form big, uniform bulbs with papery white skins and excellent texture. They prefer full sun, fertile soil, and consistent moisture. Start seeds indoors and transplant to the garden once the soil warms; bulbs mature in about 110–120 days. Ideal for northern growers and areas with long summer days.
Mild, crisp, and beautifully sweet, they are perfect for slicing fresh, caramelizing, or roasting to golden perfection.
