What does the term "hardiness zone" indicate?

The term "hardiness zone" refers to a classification that indicates the climate suitability for specific plants. This classification system, often based on average annual minimum temperatures, helps gardeners and landscapers identify which plants are most likely to thrive in a particular location based on its climate. Each zone represents a range of temperatures and helps determine the types of plants that can survive and flourish in those conditions, taking into account their tolerance to cold and heat.

This concept is crucial for successful gardening because it allows individuals to select plants that are compatible with the climate of their specific region, increasing the likelihood of healthy growth and sustainability. By understanding the hardiness zone, growers can make informed decisions about plant selection and cultivation strategies appropriate for their environment.
