The USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which perennials, shrubs and trees are most likely to thrive at a location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones. In the 2023 map, Lawrence remains in 6b with the surrounding areas updated to Zone 6b. Wichita has joined northern Oklahoma in 7a. Plants listed for Zone 6 down to Zone 2 are suited to planting outdoors in our area. Plants listed for Zone 7 and higher require higher temperatures and should be moved indoors before first frost.
