Georgia’s growing conditions run from USDA zone 6a in the high country near the North Carolina line down to zone 9b along the coast. That span matters more than any single number: out of the 65 landscape plants this site tracks, 36 are hardy across that entire range, 29 are hardy only in part of it, and zero fail everywhere in the state. The short version, almost nothing on this list is a lost cause here, but plenty depend on which end of Georgia you garden in.
What Will Not Survive a winter in Georgia
Start with the range itself: zone 6a to 9b, under the USDA Plant Hardiness Zone Map’s 2023 update, built on the 1991-2020 average annual extreme minimum temperature. That’s one of the widest state spans in this site’s dataset, and it’s the reason the answer to “what won’t grow here” is almost nothing, a plant would have to fail at both a mountain winter and a coastal winter to earn a spot on that list.
Crossing that zone range against the 65 documented plants turns up zero that fail across the whole state. Every plant this site has data for survives somewhere in Georgia. That’s not the same as saying every plant is comfortable everywhere in Georgia, the warm end of a hardiness range is usually a heat limit, not a cold one, and a plant rated hardy through zone 9b can still sulk through a coastal Georgia summer even though it technically survives the winter. Hardiness measures whether the plant lives. It says nothing about whether it thrives.
So instead of a table of failures, the practical takeaway is this: nothing on this site’s list needs to be crossed off a Georgia planting plan outright. The real decision isn’t whether a plant can survive in Georgia, it’s whether it survives in your part of Georgia, which is the question the next section actually answers. A gardener in Blairsville, up near the Tennessee border, and a gardener in Brunswick, on the coast, are working with genuinely different limits even though they share a state line.
One more distinction worth keeping straight: this hardiness data comes from a university extension plant database and describes cold and heat tolerance ranges for landscape species. It has nothing to do with the fruit-variety adaptation zones some gardeners have seen on apple charts elsewhere, those measure chill-hour requirements for fruiting, a different question entirely, and mixing the two systems is a common source of bad advice.
The plants that work in part of the state and not the rest
This is where Georgia’s size actually shows up. Of the 65 plants this site tracks, 29 are hardy in only part of the state’s 6a-9b range, meaning the plant that thrives in the Piedmont around Athens may not make it through a winter in the mountains, or may struggle through the heat near Savannah, even though both places are technically “Georgia.”
The pattern among these 29 plants sorts cleanly into three groups: those that fail at the coldest edge of the zone range, those that fail at the warmest edge, and one that fails at both ends but survives comfortably in the middle.
Fails at the warm end (zones 9a-9b)
This is by far the largest group. It includes several fruiting plants : Aronia melanocarpa, Prunus avium (sweet cherry), Pyrus communis (pear), Rubus idaeus (red raspberry), Rubus occidentalis (black raspberry), Sambucus canadensis (elderberry), Vaccinium angustifolium and Vaccinium corymbosum (blueberries) — along with a run of popular perennials: Amsonia hubrichtii, Echinacea purpurea, Iris sibirica, Phlox paniculata, and Salvia nemorosa. Shrubs in this group include Buxus sempervirens (boxwood), Fothergilla gardenii, Hydrangea paniculata, Physocarpus opulifolius, Spiraea japonica, and Viburnum dentatum. Trees include Acer saccharum (sugar maple), Pinus strobus (white pine), Quercus rubra (red oak), and Tilia americana (American basswood). All of these are documented as not hardy in zones 9a and 9b, the coastal plain and far south Georgia.
Fails at the warm end, but over a wider band
A few plants lose ground further north than the previous group: Amelanchier canadensis (shadblow serviceberry) is not hardy in 8b, 9a, or 9b; Picea abies (Norway spruce) and Thuja occidentalis (American arborvitae) drop out starting at 8a; and Syringa vulgaris (common lilac) is documented as not hardy from 7b through 9b, meaning it’s confined to a narrow northern slice of the state.
Fails at the cold end, or at both ends
Only one plant in this dataset fails at Georgia’s cold edge rather than its warm one: Ficus carica (fig), not hardy in zones 6a and 6b, which rules it out for the state’s northernmost counties. One plant threads a narrower needle than any other: Weigela florida is documented as not hardy in 7a, 7b, 9a, or 9b, meaning it’s confined to a specific middle band of the state’s range rather than either extreme.

Finding your own zone within that range is the first step before any of this applies to your yard. The insulation guide for Georgia carries a county-level zone map for the state, which is a more precise way to place your own property than guessing from a city name.
The soil and the summer they will be planted into
Georgia’s representative soil is the Tifton series, an Ultisol, old, heavily weathered, naturally acid, and low in nutrients. The surface horizon runs about pH 5.5, is 84 percent sand, 6 percent clay, and 9 percent silt, with organic matter around 0.8 percent, and it’s classified well drained. For a woody plant, drainage is the detail that matters most: winter wet kills more perennials and shrubs than winter cold does, and a soil built mostly of sand sheds water fast enough that root rot from standing water is rarely the risk in a Tifton-type garden bed.
The tradeoff is that sandy, low-organic-matter soil doesn’t hold moisture or nutrients well either. Water moves through it quickly in both directions, good news after a downpour, less good news three days later when the topsoil has already dried out.
Summer rainfall across Georgia averages about 13.6 inches over June, July, and August combined, with July the wettest month at 4.75 inches and August the driest at 4.3 inches. That’s a meaningful amount of water on paper, but the number means something different depending on what it’s falling onto. On a heavy clay soil, 13.6 inches spread across a summer would sit in the root zone for days at a time. On a Tifton-type sandy soil, the same rain drains through within a day or so, meaning a newly planted shrub can go from soaked to dry faster than the rainfall total alone would suggest. Neither the soil pH nor the rainfall figure describes any one backyard exactly, the Tifton series is what USDA maps as representative of the state, not a measurement of a particular garden bed, and a home soil test is the only way to know what’s actually under a specific plant.
When to plant, here
Two frost dates frame the planting calendar in Georgia: the last spring frost falls between March 11 and March 29, and the first fall frost arrives between November 13 and December 1, both based on 1991-2020 climate normals from the reference station used throughout this site’s Georgia data. Those are averages for one station, not a guarantee for a specific address, north Georgia and the mountains typically freeze several weeks earlier in fall than that station shows, and the coastal plain runs milder still.
The logic behind timing matters more than the calendar date itself. A newly planted tree or shrub needs time to grow roots before it’s asked to support leaf-out in spring heat or withstand a hard freeze in winter. Plant too close to either frost window and the plant is spending its first weeks fighting weather instead of building roots.
| Window | Timing | Best suited to | Main risk |
|---|---|---|---|
| Spring | After the last frost, roughly mid-to-late March | Tender perennials and plants that need a full growing season to establish before their first winter | A late cold snap can still catch new growth if planting happens too early |
| Autumn | Before the first fall frost, roughly mid-November to early December | Trees and shrubs, which benefit from cooler air and warm soil for root growth without the stress of summer heat | In the coldest parts of the state’s range, the fall window closes faster, leaving less time for roots to establish before winter |
Whichever window is used, a plant’s drought tolerance rating doesn’t apply yet. Those ratings describe an established root system, and a plant put in the ground this spring or fall needs regular water through its first season regardless of how drought-tolerant it’s rated once mature.

This plant data comes from the North Carolina Extension Gardener Plant Toolbox, a university extension database, crossed here with Georgia’s own USDA hardiness range to sort what covers the whole state from what covers only part of it. It’s worth repeating one more time: these are hardiness ranges for landscape survival, not the adaptation zones used for fruit variety selection elsewhere on this site, the two systems answer different questions and shouldn’t be read as interchangeable.
