USDA Plant Hardiness Zone Map

The USDA Plant Hardiness Zone Map is a tool that helps gardeners and landscapers determine which plants are likely to thrive in their specific geographic area. It divides regions into zones based on the average lowest temperatures during winter, ranging from 1 (coldest) to 13 (warmest). Knowing your zone helps you select plants that can survive the winter cold, increasing the chances of successful gardening. The map considers climate variations across the U.S., providing a practical guide to plant selection and gardening planning.
