When you select a plant for the garden, one of the most important things to consider is the plant's hardiness zone. The Department of Agriculture has designated eleven climate zones for the U.S. to guide gardening efforts. There are four zones in Florida—8, 9, 10, and 11.
The USDA hardiness zones are based on the average lowest temperatures, helping you choose plants that can survive the winter. Use the zones as a guide for selecting the plants best suited for your area.
Remember that Florida's long summers, high humidity, and warm nights can affect a plant's ability to survive in the appropriate zone. So use the USDA plant zones as a guide, but consult your county Extension office for more detailed information.
