North Carolina is a state with diverse landscapes, from the majestic mountains to the serene coastlines. However, these varying terrains also bring different climates that can significantly impact the types of plants that can thrive in different regions of the state. To help gardeners and horticulturists understand the unique environmental conditions in their area, the US Department of Agriculture has developed the Plant Hardiness Zone Map. This map divides the country into different zones, each representing a specific range of temperatures that plants can tolerate. In this article, we’ll explore the different plant hardiness zones in North Carolina, from the cooler mountain regions to the warmer coastal areas. By understanding these zones, you can make more informed decisions about which plants to choose for your garden or landscaping project, ensuring a healthy and thriving ecosystem in your corner of the state.
