Georgia has a range of climate zones because the state stretches from the Appalachian Mountains in the north to the coastal plains in the south.

Typical zones across the state include:

North Georgia Mountains
Zone 6b – 7a

North Georgia and the Piedmont region
Zone 7b – 8a

Atlanta metro area
Zone 8a – 8b

Central Georgia
Zone 8b

South Georgia
Zone 8b – 9a

Most of Georgia falls within Zones 7b through 9a, making it suitable for a wide variety of vegetables, fruits, and ornamental plants.

2012 vs 2023 USDA Zone Map Updates

The USDA updated the hardiness zone map in 2023 using newer climate data collected between 1991 and 2020. The previous map released in 2012 used data collected between 1976 and 2005.

This update reflects how winter temperatures have changed over time.

Key findings from the new map include:

• About half of the United States shifted into a warmer zone
• Average minimum winter temperatures increased by about 2.5°F
• Many regions warmed by about half a zone
• The updated map uses more weather stations and higher-resolution climate data

In Georgia, some areas shifted slightly warmer, particularly near urban and coastal regions.

What the Zone Changes Mean for Gardeners

The updated zones may allow gardeners to grow plants that previously struggled in colder climates.

In parts of Georgia, gardeners may now have success growing plants such as:

Figs
Camellias
Certain citrus varieties
Southern magnolia
Hardy palm varieties

However, hardiness zones only measure winter temperatures. They do not account for soil type, rainfall, humidity, or extreme summer heat.

Local growing conditions still play an important role in gardening success.

Example Plants for Georgia Growing Zones

Zone 7a – 7b
Apples, blueberries, kale

Zone 8a
Tomatoes, peppers, peaches

Zone 8b
Figs, sweet potatoes

Zone 9a
Citrus, okra, eggplant

Final Gardening Tip

Before planting any perennial plant, check the hardiness zone listed on the plant label. If your local zone falls within that plant’s recommended range, it should be able to survive winter in your area.

Combining USDA zone knowledge with local gardening experience will give you the best results.
