Discover your Mississippi growing zone with the 2023 USDA map, plus easy frost-date charts, planting calendars, and plant ideas for every region - from North Mississippi hills and Delta gardens to Piney Woods yards and Gulf Coast patios. Choose vegetables, flowers, fruits, and natives that truly thrive where you live.
Gardening in Mississippi might mean okra and field peas along a Delta fencerow, blueberries in the Piney Woods, daylilies and roses in a Jackson backyard, or palms and crape myrtles soaking up Gulf breezes in Biloxi and Gulfport. Mississippi planting zones run from the cooler northern hills to the almost subtropical coast, so what thrives in Oxford won’t be the same as what loves Pascagoula.
Using the updated 2023 USDA Plant Hardiness Zone Map (based on 1991–2020 winter lows), Mississippi now spans roughly zones 7b to 9b. The coolest pockets hug the Tennessee border, while the warmest zones trace the Gulf Coast and barrier islands. A hardiness zone describes your average annual extreme minimum temperature so you can quickly see which trees, shrubs, and perennials can reliably ride out winter in your garden.
This guide will help you understand your Mississippi growing zone, read the 2023 USDA map, time your planting around frost dates, and choose the best plants for your part of the Magnolia State.
Mississippi stretches from the hill country and Memphis suburbs in the north, across the rich Delta, central prairies and capital region, Piney Woods and coastal plain, all the way to white-sand Gulf beaches. That mix of latitude, elevation, Delta bottomlands, and Gulf influence creates several distinct gardening climates.
According to the 2023 USDA Plant Hardiness Zone Map, Mississippi’s plant hardiness zones range from about 7b to 9b, with much of the state now mapped about a half-zone warmer than earlier charts. Most gardeners fall in zones 8a–8b, with small areas of 7b in the far north and 9a–9b along the immediate Gulf Coast.
The 2023 USDA Plant Hardiness Zone Map is built from 30-year averages (1991–2020) of the coldest winter temperatures. It’s the national standard gardeners use to choose trees, shrubs, and perennials that can reliably survive winter in their area.

Although Mississippi’s planting zones run from about 7b to 9b, local conditions—river bottoms, city heat islands, piney ridges, and coastal breezes—create countless microclimates. Thinking regionally makes it easier to match plants and planting dates to your own yard.
This region includes DeSoto County suburbs of Memphis, Oxford, Tupelo, and the surrounding hills and river valleys. Winters are cooler than the rest of the state, and late frosts are more common.
Greenville, Clarksdale, Greenwood, Columbus, and Starkville sit in wide river bottoms and gently rolling uplands. Winters are moderate, summers are hot and humid, and the growing season is comfortably long.
From Jackson and Vicksburg east through Meridian and down into the Piney Woods around Hattiesburg, warm temperatures and varied soils define this region. Winters are mild and spring comes quickly.
Laurel, Picayune, Gulfport, Biloxi, Pascagoula, and Mississippi’s barrier islands are strongly influenced by the Gulf of Mexico. Frosts arrive later and end earlier here than anywhere else in the state, and some winters bring almost no freeze at all.
From chilly North Mississippi mornings to breezy Gulf Coast patios, frost dates are your best planning tool. Whether you’re gardening in Tupelo, Greenville, Starkville, Jackson, Hattiesburg, or Biloxi, your average last and first frosts help you decide when to sow cool-season crops, set out tender seedlings, and be ready with row covers in fall.
Across Mississippi, last spring frosts generally run from early–mid April in the north to late January–March near the Gulf Coast. First fall frosts typically arrive from mid–late October in northern Mississippi to early–late November across most of the south and coast.
| Region / City | Average Last Spring Frost | Average First Fall Frost | Approx. Frost-Free Days |
|---|---|---|---|
| Oxford / Tupelo (North Hills) | Early–Mid April (around Apr 5–15) | Mid–Late October (around Oct 20–30) | ~200–210 days |
| Greenville (Mississippi Delta) | Late March–Early April (around Mar 25–Apr 5) | Late October (around Oct 25–31) | ~205–215 days |
| Jackson / Meridian (Central Mississippi) | Late March (around Mar 20–31) | Late October–Mid November (around Oct 30–Nov 10) | ~220–235 days |
| Hattiesburg (Piney Woods) | Mid–Late March (around Mar 15–25) | Late October–Early November (around Oct 24–Nov 5) | ~225–235 days |
| Biloxi / Gulfport (Gulf Coast) | Late January–Mid March (around Jan 25–Mar 10) | Early–Late November (around Nov 5–28) | ~260–280 days |
Dates summarized from statewide climate and frost-date tools using 1991–2020 data; always check a local forecast and ZIP code–based lookup for the most precise information for your garden.
Use these frost windows as planning guides—your yard may act warmer or cooler depending on slope, altitude, wind, nearby pavement, and buildings. They’re long-term averages, not guarantees, so watch the forecast closely during spring warm-ups and autumn cold snaps.
Once you know your Mississippi planting zone, you can lean into your region’s strengths—cooler northern nights, long central Mississippi autumns, or nearly frost-free falls along the Gulf. Focus on cold-hardy perennials for your zone (7–9) plus heat- and humidity-tolerant annuals and vegetables, and pair them with soil-building practices that match your local conditions.
Many Mississippi native plants are perfectly tuned to local soils, rainfall, and winter lows. Combine native wildflowers, grasses, shrubs, and trees for a low-maintenance, wildlife-friendly landscape that supports pollinators and songbirds while tolerating Mississippi’s hot summers and occasional droughts.
Explore curated lists like great pollinator plants for Mississippi, monarch nectar plant collections, and guides to native grasses, shrubs, ferns, and vines to build a garden that buzzes and flutters from spring through fall.

Key zone and climate information in this article is based on the 2023 USDA Plant Hardiness Zone Map and Mississippi climate resources from extension and frost-date tools.
The 2023 USDA Plant Hardiness Zone Map places Mississippi mainly in zones 7b–9b. Northern counties along the Tennessee line are generally 7b–8a, much of the Delta and central Mississippi are 8a–8b, and the southern coastal plain and barrier islands are 8b–9b. This reflects slightly warmer winter lows than older maps.
Go to the official USDA Plant Hardiness Zone Map website and enter your city or ZIP code. The interactive map will zoom to your location and display your zone (for example, 8a or 8b). Use that zone as a baseline when choosing trees, shrubs, and perennials for your garden.
In most of northern Mississippi, the last spring frost usually occurs in early to mid-April. Central areas around Jackson often see their last frost in late March, while the Piney Woods and much of the coast typically thaw out from mid-March or earlier. On the immediate Gulf Coast, freezes are rare after late February.
Northern hills and parts of the upper Delta usually see first frost between mid and late October. Central Mississippi and the Piney Woods often frost from late October into early November. Along the Gulf Coast, the first frost may not arrive until mid–late November, and some winters bring no frost at all right on the water.
Mississippi’s average frost-free season runs roughly 200–210 days in the north, 205–235 days through the Delta and central counties, and 230–280 days along the southern and coastal areas. Many gardeners enjoy more than six months of potential warm-season growth each year.
Cool-season staples like lettuce, cabbage, broccoli, carrots, beets, peas, collards, and radishes thrive in spring and fall. Summer heat favors tomatoes, peppers, okra, southern peas, sweet potatoes, squash, cucumbers, melons, and sweet corn. In warmer zones 8b–9b, you can often grow multiple successions of warm-season crops each year.
Citrus is marginal but possible in Mississippi’s warmest pockets. Cold-hardy types such as Satsuma mandarins, kumquats, and improved Meyer lemons can survive in zone 8b–9b areas—especially near the Gulf Coast—if planted in well-drained soil, protected from north winds, and covered or wrapped during hard freezes. Container-grown citrus that is moved indoors on cold nights is an even safer option.
Yes. The USDA zone only describes your average winter low. Factors like elevation, wind exposure, urban heat, nearby pavement, water bodies, and soil moisture can make your yard act a half-zone warmer or cooler. Observing where frost lingers or melts first on your property helps you fine-tune plant choices and planting dates.
