Iceberg Lettuce is the tried and true lettuce that is an easy to grow, slow bolting crisphead. This variety has proven to be one of the most popular crispheads for years! Iceberg is a great lettuce that performs exceptionally well under warm weather conditions. This compact lettuce plant features better leaf texture and quality than other varieties. This variety resists rib discoloration and tip burn. Heirloom with light-green, crinkled, fringed outer leaves and crisp, near-white inner leaves. Medium to large heads on this classic “head lettuce.”
