Cortland F1 White Onion Bulbs and Seeds for Storage

The Cortland F1 white onion delivers high yields of thick, globe-shaped bulbs characterized by a clean white exterior and firm, dense interior. Bred specifically for long-day growing regions, this variety cultivates a mild, sweet flavor that matures into reliable winter storage crops. Growers seeking dependable volume combined with lasting shelf life will appreciate how the dense flesh resists drying out throughout the cooler months.

Commercial growers often select this strain when regional markets favor white onion premiums, as the consistent harvest size simplifies field management. You can cultivate true-to-type genetics by starting with nursery bulbs or sowing fresh seeds directly in spring soil. Extended daylight promotes uniform bulb development, allowing you to secure a steady late-autumn supply for immediate sale or long-term preservation.
