This map, which represents Iowa plant zones, is based on the 2023 revision to the USDA planting zones. This change was made due to the recent climate changes, resulting in warmer climate zones in some areas that were previously cooler. You should take time to understand your Iowa growing zones so you can choose plants that will tolerate your winter region. By choosing plants matching your zone, or one lower, they will be better equipped to survive wintry conditions. Plants grown outside your zone, or in higher zones, will generally require additional protection or relocation indoors.
