Fun Facts
- 🌱 Iceberg lettuce is called 'iceberg' because it was originally packed in ice for cross-country shipping in the early 1900s, and the name stuck despite modern refrigeration making it unnecessary.
- 🌱 Salinas, California produces nearly 70% of the nation's lettuce, and the 'Salinas' variety name honors this agricultural region's reputation for premium lettuce cultivation.
- 🌱 Lettuce is one of the few vegetables that doesn't continue to ripen after harvest, so proper timing is critical—unlike tomatoes, you can't wait for it to mature once picked.
