Featured Heat Tolerant
One of our heat tolerant lettuce varieties growing in the field.
Heat Tolerant
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? Our customer service team is ready to help.
