Upper South

Selecting plants suited to the Upper 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 Upper South region lies in USDA Plant Hardiness Zone 6 and in AHS Heat Zones 2 through 8. It typically enjoys four distinct seasons. Rain and snowfall tends to be evenly distributed throughout the seasons.

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