12 Heat-Tolerant Lettuce Varieties

While lettuce is a mainstay in diets year-round, it is actually a cool-season crop and bolts, or goes to seed, in hot weather. However, some lettuce varieties have been bred by gardeners over time to tolerate warmer temperatures and resist bolting early in the season. Plant these heat-tolerant lettuce varieties to extend your salad harvests.
