The 2012 USDA Plant Hardiness Zone Map can be used by gardeners, retailers, landscapers and growers to determine which plants are most likely to thrive in different locations. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones. Users can simply type in a ZIP Code and find the hardiness zone for that area.
