USDA Plant Hardiness Zone Map Find your location on the map below. 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. Our Nursery is in Zone is 7. The plants we grow will survive in zones 4-9. Please Note: There are many variables involved in plant hardiness. We use the best information available to provide cold hardiness zone information on our plants. Zone maps are based 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 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.
