Discover Missouri planting zones from chilly 5b in the north to warm 8a in the Bootheel. Learn how the 2023 USDA hardiness map affects your garden, find average frost dates for major cities, and explore vegetables, fruits, flowers, and native plants perfectly suited to your Missouri growing zone.
Gardening in Missouri can mean anything from prairie winds sweeping across farm fields near St. Joseph to container tomatoes on a Kansas City balcony, woodland gardens in the Ozarks, and long-season harvests in the Bootheel. Missouri planting zones span a warm, varied range of USDA hardiness zones, running roughly from zone 5b in the far north to zone 8a in the state’s southeastern Bootheel and warm river-bottom pockets.
This guide will help you understand your Missouri growing zone, read the USDA map, time your planting around frost dates, and pick the best plants for your corner of the Show-Me State.
With the updated USDA Plant Hardiness Zone Map, Missouri is now divided into a broad range of zones: 5b, 6a, 6b, 7a, 7b, and 8a. Most of the state sits in zones 6a–6b, with colder pockets in the north and the warmest zones along the Mississippi River and in the Bootheel.
The USDA Plant Hardiness Zone Map for Missouri shows how winter lows shift as you move from chilly northern counties through central farm country and into the more subtropical feel of the Ozarks and Bootheel. The map is based on 30-year averages of the coldest winter temperatures (1991–2020) and is the standard tool for choosing trees, shrubs, and perennials that can survive your local winter.

Although Missouri planting zones run from 5b to 8a, local conditions such as river bottoms, urban heat, limestone hills, and sheltered valleys create countless microclimates. Breaking Missouri into regions makes it easier to match plants to your climate—and your garden style.
This region includes Kansas City and its surrounding suburbs, stretching down toward Harrisonville and east toward Warrensburg. Winters are cold and occasionally snowy, but urban heat and rolling terrain soften extreme lows a bit. Growing seasons are long enough for most warm-season vegetables, herbs, and colorful ornamental beds.
From the Iowa border around Maryville, Kirksville, and across to Hannibal, winters are colder and the growing season a bit shorter. You’ll still enjoy plenty of summer heat, but cool nights and occasional late frosts favor hardy perennials, small fruits, and cool-season crops.
Think Columbia, Jefferson City, Sedalia, and the Lake of the Ozarks. This band of the state offers a classic four-season climate: cold winters, hot summers, and a solid mid-length growing season. Fertile soils and fairly reliable rainfall make it prime territory for both vegetables and ornamental landscapes.
As you head into Springfield, Joplin, and the Branson/Table Rock Lake region, winters turn a bit milder and the landscape more rugged. Ridges can run cooler, but sheltered hollows and towns often feel a half-zone warmer. Here you can experiment with less-hardy perennials and enjoy long tomato and pepper seasons.
Around St. Louis and along the middle Mississippi River, winters are relatively mild for the Midwest. The metro area, with its abundant pavement and rooftops, often runs slightly warmer than outlying rural areas, which helps support a broad palette of perennials, shrubs, and even a few borderline-hardy species.
Around Cape Girardeau, Poplar Bluff, Sikeston, and down into the Bootheel, Missouri starts to feel almost Southern. Winters are comparatively mild, springs come early, and the growing season is long—perfect for heat-loving vegetables, fruits, and exuberant flower gardens. The warmest river bottoms and towns may reach zone 8a.
In a state as tall and varied as Missouri, frost dates are your best planning tool. Whether you’re gardening on a breezy hilltop north of Kansas City or in a warm valley near Cape Girardeau, your average last and first frosts determine when it’s safe to plant tender crops—and when you should be ready with covers in fall.
Across Missouri, last spring frosts typically range from late March to late April, and first fall frosts usually arrive from early October to early November, depending on latitude, elevation, and local microclimates.
| Region / City | Average Last Spring Frost | Average First Fall Frost | Approx. Frost-Free Days |
|---|---|---|---|
| Kansas City (Western MO) | Early–Mid April (Apr 1–10) | Late October (Oct 21–31) | ~190–200 days |
| Columbia / Jefferson City (Central MO) | Early–Mid April (Apr 1–10) | Late October (Oct 21–31) | ~190–200 days |
| Springfield (Southwest MO) | Early–Mid April (Apr 1–10) | Late October (Oct 21–31) | ~190–200 days |
| St. Louis (Eastern MO) | Late March–Early April (around Mar 28–Apr 7) | Late October–Early November (around Oct 31–Nov 5) | ~200–210 days |
| Cape Girardeau / Bootheel (Southeast MO) | Early–Mid April (around Apr 5–12) | Late October–Early November (around Oct 25–Nov 5) | ~200–215 days |
Dates summarized from regional climate and frost-date tools; always check a local forecast and ZIP-code–based lookup for the most precise information for your garden.
Use these frost dates as a planning guide—your yard may be warmer or cooler depending on elevation, slope, wind, surrounding pavement, nearby water, and building heat. They’re long-term averages, not guarantees, so keep an eye on the forecast during spring and fall cold snaps.
Once you know your Missouri planting zone, you can lean into your region’s strengths—whether that’s a cooler season up north or the long, warm summers of the Bootheel and Ozarks. Focus on cold-hardy staples in zones 5–6 and heat-loving crops and ornamentals in zones 6–8, while choosing perennials rated for your specific hardiness zone.
Missouri native plants are perfectly tuned to local soils, moisture, and winter cold. Mix native wildflowers, grasses, shrubs, and trees for a low-maintenance, wildlife-friendly landscape that supports pollinators, songbirds, and beneficial insects.

Missouri currently spans a wide range of USDA planting zones, from 5b in the cooler northern counties to 8a in the warmest river-bottom and Bootheel areas. Most of the state falls in zones 6a–6b, with 7a–7b and small 8a pockets in southeast and urban locations.
The latest USDA hardiness map uses more recent climate data and finer-scale weather information. Many parts of Missouri shifted about a half-zone warmer, especially in central and southern areas. Gardeners who were previously listed as zone 5b–6a are now often mapped as 6a–6b, 7a, or even 8a in the mildest locations.
Average last spring frosts in Missouri generally occur between late March and late April. Cities like Kansas City, Columbia, Springfield, and St. Louis often see their final frosts around early to mid-April. Northern locations can frost later, while the Bootheel and warm urban areas may become frost-free earlier.
In much of Missouri, the first fall frost typically arrives in October. Central and western cities such as Columbia, Jefferson City, Springfield, and Kansas City usually see first frosts between late October and early November. Northern counties may frost earlier, while the warmest southern and 8a pockets often frost last.
Yes, with the right site and zone. Peaches and some sweet cherries generally perform best in Missouri’s warmer 6b–8a regions, especially on slopes with good air drainage that limit frost damage. Cold-hardy figs, American persimmons, and select pomegranates may succeed in protected 7b–8a microclimates and warm urban gardens.
Zones 6 and 7, which cover much of Missouri, are excellent for both cool- and warm-season crops. Cool-weather crops like lettuce, spinach, peas, broccoli, and cabbage thrive in spring and fall. Warm-season favorites—tomatoes, peppers, beans, squash, cucumbers, sweet corn, okra, and sweet potatoes—produce heavily in the long, hot summers.
Microclimates can make a garden feel effectively a half- to full zone warmer or cooler than the official map. River bottoms and paved urban neighborhoods often stay warmer, pushing conditions toward zone 7 or 8. Exposed ridges, low frost pockets, and open fields can run cooler and experience earlier frosts than surrounding areas.
Missouri native plants such as purple coneflower, black-eyed Susan, liatris, goldenrod, little bluestem, prairie dropseed, eastern redbud, flowering dogwood, and native oaks and hickories are well adapted to local soils and climate. They support birds, bees, and butterflies, and typically need less water and fertilizer than many non-native ornamentals.
