Description: "This Florida map is from the Plant Hardiness Zone Map of the contiguous United States prepared by the National Arboretum (USDA Agricultural Research Service 1965). The cold hardiness zones are based upon average minimum winter temperatures, that is, the lowest temperature in each year." —Elbert L. Little, Jr. The zones are as follows: Zone 8b, the coldest climate, 15 degrees; Zone 9a, 20 degrees; Zone 9b, 25 degrees; Zone 10a, 30 degrees; Zone 10b, 35 degrees.
