USDA Hardiness Zone Map
Visit the USDA's web site for more information on the Hardiness Zone Map.
USDA Plant Hardiness Zone Map for Kansas and nearby area.
Most of the northern part of Kansas is zone 5b, and most of the southern part of Kansas is zone 6a. Thus, plants rated to zone 6 may not survive the winter in northern Kansas. Not all plants have been thoroughly tested to determine what zone they are truly hardy to. The hardiness zone for each perennial is listed in our Descriptive Plant Catalog.
