No matter what time of year it is, it is extremely important to understand your plant hardiness zone if you are gardening or landscaping.
Before you get started, take a moment to review the 美国农业部植物抗寒区地图 适合你的地区. Knowing your hardiness zone will help you pick the plants that are appropriate for where you live. The hardiness zone is most important for perennials and shrubs that will live through the winter.
Picking plants that are appropriate for your zone will aid in your gardening success and prevent frustrations. No one wants to see their hard work and money go to waste when they realize their plants didn’t make it through the winter.

美国农业部植物抗寒区地图
You have probably seen this color-coded map before and may have wondered, what does it all mean?
The 2023 美国农业部植物抗寒区地图 is the standard by which gardeners and growers can determine which plants are most likely to thrive at a location. (planthardiness.农业研究所.美国农业部.政府)
解释耐寒区地图
The Hardiness Zone Map will show the average annual extreme minimum temperature by location. Average annual extreme minimum temperature ranges are represented by different colors. The different colors are called zones and have an accompanying number. The color key on the map represents these minimum extreme temperatures and their zone number (for example, 35-40度为10b区).
To show an example of how this works, we will use the states of 西维吉尼亚州 and 维吉尼亚州.
根据 西维吉尼亚州 map, this state experiences the extreme minimum temperatures of -20 to -15 and 0 to 5 depending on the location within the state. What this tells us is there are areas of 西维吉尼亚州 that get much colder in the winter months than other areas. Plants will need to be hardier to withstand the low temperatures of 西维吉尼亚州 zone 5a and 5b than in the state’s warmer zone 7a.
根据 维吉尼亚州 map, this state experiences the extreme minimum temperatures of -20 to -15 and 10 to 15 depending on the location within the state. 维吉尼亚州 experiences a wider range of minimum temperatures. Plants that have the hardiness zone appropriate for 维吉尼亚州 Beach may not survive the winter months in the cooler mountain areas west of Charlottesville.
找到你的领域
To learn what zone you live in, visit the USDA Agricultural Research Service website. You can search for your hardiness zone by entering your ZIP Code. Once you enter the ZIP Code, it will give the exact zone for that location.
Another way to find your zone is to use the interactive map, which allows you to click on your state. Once you click on your state, you will be shown the color-coded map. Find your area, then use the map key to find your zone number.
检查植物的耐寒性
You know your zone, so how do you find appropriate plants?
When choosing plants, make sure to refer to the tag. The tag will show the hardiness temperature along with other important information. Some plant tags will have the actual zone number (for example, 5a). Some tags will show the ‘hardy to’ temperature. Pick plants that are hardy to your zone, so they are more likely to live through your location’s winter months.
Make sure to pay attention to the additional information on the tag. 还有植物的抗寒性, you will need to understand the other conditions necessary for that plant’s success. If you are still unsure if the plant will work in a specific area in your yard, ask the gardening center sales associate for assistance.
Gardening can be rewarding and, at times, frustrating. Get in the zone and know your location’s USDA plant hardiness zone number to improve your gardening success. Planting plants appropriate for where you live can reward you with ongoing growth and beauty.
If you are interested in learning more about plants that work in your area, contact your local county extension office. Local extensions may have volunteer Master Gardeners who are trained to assist you.
