Description
Lactuca sativa var. longifolia produces upright, elongated heads with firm, crisp leaves and a strong central rib, making it the classic lettuce for Caesar salads. Its flavor is hearty and slightly sweet, and the leaves remain stable even when lightly sautéed or grilled.
Care instructions
Plant in nutrient-rich, deep soil and water evenly to keep heads firm and juicy. It is more robust and heat-tolerant than leaf lettuce, but will bolt under prolonged drought, mulching helps retain moisture. Harvest the entire head once it is tightly closed, or continually pick outer leaves as needed.
