Regions / South
Selecting plants suited to the climate of the South region 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 South region lies in USDA Plant Hardiness Zones 6-11 and in AHS Heat Zones 2 through 12. With the exception of a few high-elevation areas, most of the South experiences extremely hot summers with high humidity, and mild winters. Because of the intense heat and humidity, perennial gardening is mostly confined to lightly shaded areas.
