Great Lakes Mesa 659 crisphead is another lettuce often found at grocery stores. Round iceberg heads are strong and firm with uniform leaves. Super multitasker.
Leaves are light green and round with a crisp cool texture. These heads are slow to bolt and can handle the heat. They have productive yields and can handle both heat and cool weather, so plant seeds in spring or fall. Leaves are great to make a wedge salad, add to sandwiches or use to make lettuce cups.
