USDA Plant Hardiness Zone Map
Find your location on the map, or you can find your hardiness zone easily by using your zip code on the website garden.org
This will tell you what growing zone you are in. Each plant has two numbers besides the Growing Zone, ex. 6-9.
This means the plant will grow in Zone 6, 7, 8 and 9.
Please Note: There are many variables involved in plant hardiness. We use the best information available to us to provide cold hardiness zone information on our plants. Zone maps are bases on multi-year temperature data. Maps using data from recent, milder winters have shifted many areas one zone warmer. To further complicate matters, in any given year temperatures can fluctuate a zone or even 2, up or down. Such factors as lack of snow cover, early or later extremes and protections from mulch or buildings can also have an effect. We hope this information is a helpful guide.
