Flowers to Grow in Georgia

Contents

The state of Georgia exemplifies magnificent natural beauty, unlike any other southern state. Georgia is home to beaches, canyons, forests, marshes, mountains, and waterfalls, each with a unique range of plant life. But what about flowers? Are there certain types of flowers that will thrive a bit better in Georgia’s temperamental climate?

While many flowers can be planted in Georgia as annual flowers, it takes a hardy perennial to survive the heat and humidity of Georgia’s summers. Because of the heat, and humidity, there are certain flowers that are going to be more likely to thrive. This is true regardless if it’s a single season flower, or something you expect to come back year after year.

Not only is it important to find the right flower fit, but best gardening practices, including proper watering, trimming, or pruning, give flowers – even those not native to Georgia – the best chance of survival.

Flowers That Thrive in Georgia

Georgia has a humid subtropical climate. Even though the state has a variety of terrains, it still has a distinction between all four seasons. Summers are long, hot, and humid, while winters are short and mild. Fall and spring tend to vary concerning the last freeze. There aren’t frequent extreme temperatures that can be harmful to your flowers.

Other than being mindful of the climate, there are some other factors that Georgia flowers need to thrive.

It is no secret that good draining soil is vital to a flower’s health – or any plant. Most of the earth in Georgia has acidic pH levels, so adjustments have to be made, like adding lime to neutralize the soil pH. According to the USDA Plant Hardiness Zone Map, Georgia lives in zones 6 through 9.
