Unpredictable weather cycles that range from toasting heat to blustery chills can make this a challenge, especially in places like Oklahoma. To help gardeners and landscapers clarify climate zones throughout the country, the U.S. Department of Agriculture provides a map based on average annual minimum winter temperatures from the past 30 years.
