Lettuce ‘Great Lakes’ Seeds

Heirloom crisphead variety that is a true garden workhorse, originally developed to stand up to the heat of the summer while maintaining a tight, glass-like crunch that modern, supermarket varieties simply cannot replicate.

‘Great Lakes’ is for those who crave a classic, refreshing iceberg-style lettuce. It produces large, heavy, and tightly folded heads with an attractive, frilled-edge appearance. Unlike delicate leaf lettuces, this variety holds its crisp, juicy texture long after harvest. It is slow-to-bolt and remarkably resistant to tip-burn, making it a reliable performer even as temperatures begin to climb. Whether you’re crafting the base of a classic garden salad or stacking crisp leaves onto a homemade burger, ‘Great Lakes’ delivers a clean, sweet, and satisfying snap in every bite.

• Unrivalled Crispness: Famous for its dense, firm texture and refreshing, watery snap.

• Heat-Tolerant Reliability: Specifically bred for better performance in warmer conditions, extending your lettuce harvest into the shoulder seasons.

• Slow-to-Bolt: Maintains quality for longer in the garden, giving you more time to harvest perfectly matured heads.

• Uniform & Productive: Forms large, solid, beautifully frilled heads that are consistent in size and quality.

• Versatile Kitchen Staple: The quintessential "crunch" lettuce—perfect for salads, sandwiches, and wraps.
