Tropical South

Selecting plants suited to the Tropical South climate is a key step to success.

Various initiatives have taken place to determine how well plants would withstand the cold winter temperatures (Plant Hardiness Zones) or when plants would start suffering from the heat (Plant Heat Zones).

The Tropical South region lies in USDA Plant Hardiness Zones 10-11 and in AHS Heat Zones 10 through 12.

If you know your hardiness zone and heat zone, find the best plants or exciting garden ideas for your geographic area.
