Why Fall Is the Best Time to Plant Perennials in Georgia (+ 6 Plants to Grow Now)

When the first hints of fall arrive, it’s tempting to think another gardening season is winding down.

The tomatoes are slowing. The summer flowers are fading. The mornings finally have a little crispness to them. Surely it’s time to clean up the garden, put away the shovel, and start dreaming about what you’ll plant next spring...right?

Not so fast.

Here in Georgia, fall is actually one of the best times of year to plant perennials, shrubs, and many native plants. And if you want a garden filled with established plants, flowers, pollinators, and medicinal herbs next year, some of that work starts now.

The secret is something gardeners learn to appreciate very quickly: what’s happening below the soil can be just as important as what’s happening above it.

Why Is Fall the Best Time to Plant Perennials?

Spring gets most of the gardening glory, but fall gives newly planted perennials a pretty wonderful combination: warm soil + cooler air.

After surviving a Georgia summer, we gardeners appreciate cooler temperatures, and our plants do, too.

The intense heat that can stress a newly transplanted perennial begins to disappear, while the soil retains enough warmth for roots to continue growing. Instead of putting all their energy into producing flowers and foliage while simultaneously trying to survive the heat, plants can concentrate on getting established underground.

University of Georgia Cooperative Extension recommends fall and winter planting for many woody ornamentals and herbaceous perennials for exactly this reason. Cooler temperatures mean less demand for water and nutrients above ground, while the plant can continue developing its root system.

And that gives your garden a head start.

By the time spring arrives, your fall-planted perennials aren't starting from scratch. They’ve already had time to settle into their new home and develop roots that can help support the rush of new spring growth.

Fall planting can also mean less watering.

Another bonus? Cooler temperatures mean less water is lost through evaporation and plant foliage, so newly planted perennials generally require less irrigation than they would during our hot Georgia summers.

That doesn't mean you can plant them and forget them, new plants still need consistent moisture while establishing, but Mother Nature is certainly lending a helping hand.

Plant in Fall for a Better Garden Next Year

There’s another reason we love planting perennials this time of year: fall gardening is an investment in future seasons.

Perennials return year after year when they're happy in their location. And when you choose plants that provide food and habitat for pollinators and other wildlife, your planting choices become an investment in the ecosystem around your home, too.

So while your new plant may not look particularly exciting after winter dormancy arrives, don't underestimate what it's doing beneath the soil.

Plant now. Let those roots get to work. Then wait for the spring show.

Ready to get digging? Here are six perennial favorites we're especially excited about planting this fall.

1. Echinacea

Echinacea purpurea

There are very few plants that check as many boxes in a wellness garden as Echinacea.

Also known as coneflower, this hardy perennial produces those instantly recognizable daisy-like blooms that bees and butterflies adore. Once the flowers fade, leaving the seed heads standing can also provide winter interest and a food source for birds.

Echinacea loves sunshine and well-draining soil, and once established, it can tolerate dry conditions. That makes it particularly useful for sunny borders, pollinator gardens, cottage gardens, and naturalized areas.

And, of course, Echinacea has a long history as a medicinal herb, making it right at home in a Planted Wellness garden.

Plant it for: pollinators, summer flowers, bird habitat, medicinal gardens, and an easy-care perennial that comes back year after year.

2. St. John’s Wort

Hypericum

If cheerful yellow flowers are your thing, make a little room for St. John’s Wort.

Hypericum species are hardy perennial plants that can bring sunny yellow blooms and attractive foliage to the landscape. Depending on the species and cultivar, St. John’s Wort can work beautifully in perennial beds, naturalized areas, borders, or as a low-growing shrub.

Give it a location with the appropriate sunlight and drainage for your particular variety, and let it settle in through the cooler months.

Plant it for: bright summer color, perennial structure, and a plant with a fascinating history in traditional herbalism.

3. Baptisia

Baptisia spp.

Want a perennial that gets better with age? Meet Baptisia.

Also known as false indigo, Baptisia develops into a substantial, shrub-like herbaceous perennial with beautiful spring flower spikes. After flowering, its seedpods provide another layer of texture and interest.

One of Baptisia's greatest strengths is what you don't see: its root system. Once established, Baptisia can become remarkably resilient and long-lived.

That also means this is one plant you'll want to place thoughtfully. Rather than planning to move it around later, choose a sunny location where it has room to mature—and let it make itself at home.

Plant it for: spring blooms, structure, low-maintenance perennial beds, and long-term garden impact.

4. American Beautyberry

Callicarpa americana

If you've ever spotted clusters of almost impossibly purple berries glowing along a woodland edge in fall, there's a good chance you've met American Beautyberry.

And yes, it really is that pretty.

This native perennial understory shrub typically grows around 3–5 feet tall and produces clusters of brilliant purple berries in fall and early winter. Those berries aren't just beautiful: they also provide a natural food source for numerous species of birds.

Beautyberry is particularly useful for those tricky shadier areas of the landscape. It prefers part shade and moist soil, making it a lovely choice around woodland edges or lower areas of the yard that naturally hold more moisture.

It gives us exactly what we want from a native landscape plant: beauty for us and resources for the wildlife around us.

Plant it for: native gardens, bird habitat, fall color, woodland edges, and part-shade landscapes.

5. Spotted Bee Balm

Monarda punctata

If your garden philosophy is essentially “more pollinators, please,” Spotted Bee Balm deserves a spot on your list.

A member of the Monarda genus, this distinctive native perennial produces unusual stacked flowers and bracts that look almost like tiny botanical layer cakes. The blooms provide nectar for an impressive variety of beneficial insects.

Its unusual shape also gives it a completely different look from many of the traditional flowers in a perennial border, making it as interesting to us plant nerds as it is useful to the insects visiting the garden.

Plant it alongside other sun-loving native perennials to begin building a landscape that offers food and habitat instead of simply looking pretty.

Although, luckily, it does that too.

Plant it for: native plantings, pollinator gardens, biodiversity, and wonderfully unusual blooms.

6. Anise Hyssop

Agastache foeniculum

Anise Hyssop is one of those plants that earns its garden real estate.

This North American native perennial grows to around three feet tall and produces upright flowers from summer into fall. Its long nectar season makes it especially valuable to bumblebees, butterflies, and hummingbirds, while leaving the seed heads standing can provide food for songbirds such as goldfinches.

Once established, it's also drought tolerant and relatively easy to grow in full sun to part shade with well-draining soil.

And then there's the fragrance.

The leaves and blooms have a lovely anise-licorice scent, and both have a history of use as an herbal tea. In other words, this is exactly the kind of multitasking plant we love: beautiful, useful, fragrant, and beneficial to wildlife.

Try planting three together in a triangle for a fuller, bushier display.

Plant it for: bees, butterflies, hummingbirds, songbirds, fragrance, herbal gardens, and a long season of blooms.

A Few Tips Before You Plant

Fall planting is forgiving, but a little preparation goes a long way.

First, match the plant to the place. Pay attention to how much sun your planting area actually receives and whether the soil tends to stay moist or dry quickly. A sun-loving prairie perennial and an understory shrub may both be Georgia natives, but that doesn't mean they'll be equally happy in the same corner of your yard.

Next, give your plant a good drink after planting and continue watering while it establishes, particularly if we're having a dry fall.

Adding mulch can help conserve moisture and insulate the soil as temperatures change, but don't pile mulch directly against the crown or stems of the plant.

And finally, don't panic when some of your herbaceous perennials disappear for winter.

They aren't dead. They're resting.

Their roots are still down there getting acquainted with their new home—and preparing for what's next.

Your Spring Garden Starts Now

Gardening has a lovely way of teaching us to think a season or two ahead.

The Echinacea you tuck into the ground this fall becomes next summer's butterfly stop. The little Beautyberry becomes future shelter and food for backyard birds. The Anise Hyssop establishes its roots now so it can send up fragrant flowers buzzing with bees next season.

That’s the beauty of planting perennials: you aren't planting for a moment. You're planting for years.

So don't put those garden gloves away quite yet.

Fall is calling, and there are still plenty of things worth planting.
