Plant Hardiness Zones
The USDA Plant Hardiness Zone Map is an essential tool for all landscapers and gardeners, whether professionals or weekend do-it-yourselfers. This simple and free tool will help ensure you select only the correct plants, shrubs, or trees for your region. If you do not follow this guide you risk the health of your plant, and ultimately your time and money.
The Map was designed to show the average annual minimum temperature range throughout the United States, Canada, and Mexico. There are 11 different zones that describe the minimum temperature that can be expected. The zones were divided based on a 10 degree Fahrenheit difference in the average annual minimum temperature.
It is important to understand the zones in order to select a plant that will survive the winter in your region. This is called the plant's winter hardiness. The winter hardiness of the plant is one of the most crucial factors for the survival and environmental adaptation of the plant.
