In our trials, we test and select varieties that can endure heat successfully. This includes heat-tolerant versions of cool-weather crops; for example, heat-tolerant lettuce, spinach, broccoli, and kale varieties that can help keep you in greens throughout the hot summer months. We also seek out highly heat-tolerant versions of warm-weather crops, such as heat-tolerant tomatoes with the ability to set fruit even during the summer heat of southern growing zones. Choose from a large assortment of heat-tolerant vegetable seed varieties to fill your seasonal planting slots. Not sure of what to choose for your growing zone?
