Overview
Great Lakes is the original American crisphead, the work of W.D. Blystone at Michigan's agricultural experiment station, released in 1941, and an All-America Selection in 1944. It defined the iceberg type. Like all crispheads it heads only in cool weather; if warmth arrives first, plants bolt without forming the firm head, and it needs a long season from transplant. Start seed indoors and set out into a cool-season bed, then cut when the head is firm. In hot-summer regions, timing must be precise, and many gardeners find romaine or butterhead types easier.
