Lactuca sativa var. capitata 'Iceberg'
Iceberg lettuce
Common names: Iceberg salad, Crack lettuce
Category imageThis description was machine-translated.
Description
The Iceberg lettuce forms a firm, spherical head of crisp, pale green leaves and epitomizes freshness and bite. It is heat‑tolerant and stores longer than loose‑leaf lettuce, retaining its characteristic crunch in the refrigerator for days.
Care instructions
Plant seedlings in nutrient‑rich soil and water generously and evenly—Iceberg lettuce requires ample moisture for firm heads, especially during head formation. Keep sufficient spacing so heads can fully develop, and harvest when they feel firm before they bolt. A mulch layer keeps the soil cool and moist.
