Kansas is in the U.S. Department of Agriculture's winter hardiness zones 5 and 6. According to Kansas State University's Cooperative Extension Service, peaches are viable options for fruit trees in the Sunflower State. Peaches are perhaps best grown in the southeastern third of Kansas, or zone 6, as winters are milder and soils more suitable. While peach trees can be grown in other parts of Kansas, spring frosts, low winter temperatures, wind and heavy-textured alkaline soils are environmental stresses peach trees must overcome to prosper.
Producing its firm peaches in August, "Cresthaven" is a variety that has good winter hardiness. The variety blooms later in spring, potentially avoiding the late frosts that might kill the flower buds. The yellow peaches become heavily covered in a deep orange-red blush when ripe. With excellent flavor, the yellow flesh tends to become red around the pit, but freely pulls away from it, making it a "freestone" peach variety.
"Reliance" produces medium or large peaches with yellow skin blushed with a dull red. This variety has outstanding winter cold hardiness, according to the "Sunset Western Garden Book" and the University of Missouri. The soft, yellow flesh has a sweet and delicious flavor and pulls easily from the pit. It is considered an "early season" peach that ripens in July.
The University of Missouri recommends "Madison" in the colder reaches of Missouri, which is similar to western counties in Kansas when it comes to winter weather conditions. This peach variety produces bright, coral-red peaches in August. The firm, fibrous, golden-yellow flesh is sweet and mildly flavored.
"Jayhaven" is a peach variety recommended for Oklahoma gardens, which can also handle similar conditions in central and eastern Kansas. It has good winter hardiness and yields large yellow fruits that are freestone. It ripens in mid-July across Kansas, slightly earlier than Oklahoma counties that are further south.
