Plant Hardiness Zones

When looking at information on a plant, you'll often see a "zone" number listed. The USDA has designated ten "hardiness zones," which are based on the minimum temperature in the region. Three zones cover Florida: 8, 9, and 10 (plus a subtropical zone 11 on some maps). While this number helps you decide whether a plant can survive winter in your area, there are many other factors you should consider, such as how much heat the plant can handle, type of soil and amount of sunlight it requires.
