Description

Lettuce 'Great Lakes' (Lactuca sativa), an All-America Selections winner introduced in 1944, is a classic open-pollinated heirloom crisphead iceberg type celebrated for its exceptional crunch, heat tolerance, and bolt resistance. Producing firm, heavy, tightly packed heads 10 to 12 inches in diameter, it features fringed, dark green outer wrapper leaves surrounding a crunchy, pale green to white interior core. Carrying a mild, sweet, refreshing flavor, Great Lakes stands up remarkably well to summer temperatures without turning bitter. An essential staple for fresh garden salads, wraps, burgers, and wedge salad preparations, this variety delivers consistent cool-season harvests.
