The USDA Plant Hardiness Zone Map is produced by the United States Department of Agriculture, and it is the standard by which you can determine which plants are most likely to thrive in any specific location. The map is divided into 10°F sections dependent on the average annual minimum winter temperature.
The zones identified in Fine Gardening are based on several sources and should be treated as general guidelines when selecting plants for your garden. Many other factors may come into play in determining healthy plant growth. Microclimates, wind, soil type, soil moisture, humidity, snow, and winter sunshine may greatly affect the adaptability of plants. For more information and to zoom in on your area, visit the map at the USDA website, where you can type in your zip code to find out your hardiness zone.

Finding plant hardiness zones
Most plants purchased from a nursery or garden center will have the hardiness zone information on the tag.
A plant purchased at a nursery or garden center will have the hardiness zone information on the plant tag, if available. If none is available, you can search online for the hardiness zones using the plant name and cultivar, if known.
In this example, the plant tag mentions that Diamond Frost® euphorbia should be considered an annual in all zones except zones 10a–11b, meaning it is not hardy in less temperate zones and will die if exposed to cold or extreme winter weather.
Searching for plant information online
There are many sources online to find plant information including zone, region, and plant care needs. The grower of a cultivar is a great place to start for specific information. Other sites such as the Missouri Botanical Garden have well-established and trustworthy records that can be used for reference.
