Learn how the new 2023 USDA hardiness zones shape gardening in Kansas. Find your zone, understand frost dates, and explore vegetables, fruits, flowers, and natives that truly thrive from the High Plains to Wichita and Kansas City. Turn your yard into a resilient, pollinator-friendly Sunflower State garden.
Gardening in Kansas can mean anything from tough, windy High Plains beds near Goodland and Garden City to lush shade gardens in Kansas City suburbs, prairie-style borders in the Flint Hills, and long-season harvests around Wichita and the southeast. Kansas planting zones cover a warm, continental spread of USDA hardiness zones, running roughly from zone 5b in the far north and northwest to zone 7a in much of south-central and southeastern Kansas, with most gardeners in the 6a–6b range.
This guide will help you understand your Kansas growing zone, read the USDA map, time your planting around frost dates, and pick the best plants for your corner of the Sunflower State.
With the updated 2023 USDA Plant Hardiness Zone Map, Kansas is now divided mainly into zones 5b, 6a, 6b, and 7a. Most of the state falls in zones 6a–6b, with colder pockets of zone 5b along the Nebraska and Colorado borders and expanded areas of zone 7a around Wichita and the southeast.
The USDA Plant Hardiness Zone Map for Kansas shows how winter lows moderate as you move from the colder High Plains in the northwest through central farm country and into the relatively milder south-central and southeastern counties. 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 Kansas planting zones run mainly from 5b to 7a, local conditions—windbreaks, prairie exposures, river bottoms, urban heat, and sheltered courtyards—create countless microclimates. Breaking Kansas into regions makes it easier to match plants to your climate and gardening style.
This region includes Goodland, Colby, Oberlin, and nearby High Plains communities. Winters are cold, snow and wind are common, and the growing season is shorter than in eastern Kansas. Tough prairie perennials, drought-tolerant shrubs, and cool-season vegetables do especially well here.
From Concordia and Clay Center down through Salina and Hays, summers are hot, winters cold, and the growing season is moderate in length. Deep prairie soils respond well to vegetables, small fruits, and prairie-style flower borders.
Kansas City, KS; Overland Park; Olathe; Lenexa; and nearby communities, along with Lawrence and Leavenworth, enjoy relatively long frost-free seasons and strong urban heat effects. Most neighborhoods are zone 6b, with older, tree-shaded suburbs and river bottoms often feeling a touch warmer.
Topeka, Manhattan, Junction City, and Emporia sit in the heart of the Flint Hills and central Kansas. Here you’ll find a classic four-season climate, rolling prairie hills, and soils that, once improved with compost, support everything from cool-season greens to flowering shrubs and native grasses.
Wichita, Hutchinson, Derby, Newton, and nearby towns enjoy relatively mild winter lows for Kansas, plus long, warm summers. This zone is ideal for heat-loving crops like tomatoes, peppers, okra, and sweet potatoes, along with ornamentals that appreciate hot, sunny conditions.
In Pittsburg, Independence, Chanute, and other southeast towns, Kansas begins to feel almost Southern: winters are comparatively mild, rainfall is generous, and the growing season is long. You can grow a wide variety of fruits, vegetables, and exuberant flower gardens, plus many of the state’s best native prairie and woodland plants.
In a state as wide and windy as Kansas, frost dates are your best planning tool. Whether you’re gardening on a breezy High Plains ridge or in a protected Wichita backyard, 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 Kansas, last spring frosts typically range from early April to mid-May, and first fall frosts usually arrive from late September to late October, depending on latitude, elevation, and local microclimates.
| Region / City | Average Last Spring Frost | Average First Fall Frost | Approx. Frost-Free Days |
|---|---|---|---|
| Kansas City, KS (Northeast KS) | Mid April (around Apr 11–20) | Early–Mid October (around Oct 1–10) | ~170–180 days |
| Topeka / Lawrence (NE & Flint Hills Edge) | Mid–Late April (around Apr 15–25) | Early–Mid October (around Oct 1–12) | ~165–180 days |
| Manhattan / Salina (Central KS) | Late April–Early May (around Apr 25–May 5) | Early–Mid October (around Oct 5–15) | ~155–170 days |
| Wichita / Hutchinson (South-Central KS) | Late April–Early May (around Apr 25–May 5) | Mid–Late October (around Oct 15–28) | ~165–185 days |
| Garden City / Goodland (Southwest & Northwest High Plains) | Early–Mid May (around May 5–16) | Late September–Early October (around Sept 23–Oct 5) | ~130–155 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, wind exposure, slope, 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 Kansas planting zone, you can lean into your region’s strengths—whether that’s a cooler, windier season in the High Plains or the long, warm summers of Wichita and southeast Kansas. Focus on cold-hardy staples in zones 5–6 and heat-loving crops and ornamentals in zones 6–7, while choosing perennials rated for your specific hardiness zone.
Kansas native plants are perfectly tuned to local soils, wind, and winter cold. Mix native wildflowers, grasses, shrubs, and trees for a low-maintenance, wildlife-friendly landscape that supports pollinators, songbirds, and beneficial insects.

Under the updated 2023 USDA Plant Hardiness Zone Map, most of Kansas lies in zones 6a and 6b. Cooler pockets in the far north and northwest are zone 5b, while warmer south-central and southeastern areas, including much of Wichita and Pittsburg, reach zone 7a.
Use the USDA’s interactive Plant Hardiness Zone Map. Enter your ZIP code at the official site and zoom in; you’ll see your zone to the half-step (5b, 6a, 6b, or 7a). Then choose trees, shrubs, and perennials labeled hardy to your zone or colder.
In most of Kansas, the average last spring frost falls between early April and early May. Northeast cities like Kansas City and Lawrence typically see last frost in mid April, while central and south-central areas such as Salina and Wichita often frost for the last time in late April or very early May. High Plains locations like Goodland can freeze into mid May.
Northern and northwestern Kansas often see first frost between late September and early October. Central and northeast regions, including Topeka and Manhattan, tend to frost in early to mid October. South-central and southeastern areas like Wichita and Pittsburg usually freeze later, from mid to late October.
Kansas averages about 130–185 frost-free days, depending on location. High Plains towns such as Goodland may have only around 130–150 frost-free days, while south-central and southeastern areas like Wichita can enjoy roughly 165–185 days between the last spring frost and the first fall frost.
Cool-season crops like lettuce, peas, spinach, broccoli, cabbage, carrots, and radishes thrive in spring and fall. Warm-season staples—tomatoes, peppers, squash, cucumbers, beans, sweet corn, and, in warmer zones, okra and sweet potatoes—perform well when planted after the last frost and given full sun and consistent moisture.
Yes. Kansas native plants such as purple coneflower, black-eyed Susan, little bluestem, switchgrass, butterfly milkweed, and aromatic aster evolved with the state’s wind, heat, and variable rainfall. They typically need less water and fertilizer once established and provide excellent food and habitat for pollinators and birds.
Many fruit trees do well in Kansas if matched to your zone. Cold-hardy apples, pears, tart cherries, and plums can be grown across most of the state. In warmer 6b–7a areas, especially around Wichita and southeast Kansas, peaches, certain sweet cherries, and hardy figs or persimmons may succeed in protected sites.
