Caldwell F1 is a widely adaptable long-day yellow onion variety that produces super colossal, globe-shaped bulbs with a rich bronze outer scale. These bulbs have a high ratio of single centers, making them ideal for storage and culinary use. The bulbs store well for 5 to 6 months, providing extended usability after harvest.
The plants feature a refined neck and a robust root system, contributing to their strong growth and resilience. Caldwell F1 onions also exhibit high resistance to Fusarium and Pink Root diseases, making them a reliable choice for growers seeking durable and productive onion varieties.
