Hardiness zones are geographic areas defined by temperature ranges that determine which plants can survive winter lows. The USDA first developed the zones, with zone 1 being the coldest and zone 10 the warmest. The document provides examples of specific plants that grow in each zone, from zone 1 plants like crowberry and dwarf birch to zone 10 plants such as bougainvillea and royal palm.

2. What is Hardiness Zone? A hardiness zone is a geographically-defined zone in which a specific category of plant life is capable of growing, as defined by temperature hardiness, or ability to withstand the minimum temperatures of the zone. The zones were first developed by the United States Department of Agriculture (USDA), and have subsequently been adopted elsewhere.
