Xeriscaping is a sustainable landscaping method that reduces the need for irrigation
by utilizing drought-tolerant plants. It is especially beneficial in arid and semi-
arid regions, but it can also be implemented in various climates to conserve water
and create beautiful, low-maintenance gardens. The key to a successful xeriscape
is selecting plants that are well-adapted to the local climate.

The U.S. Department of Agriculture (USDA) defines garden hardiness zones based on
average annual minimum winter temperatures. These zones help gardeners and landscapers
determine which plants will thrive in specific regions. Below is a detailed guide
to the best xeriscaping plants for each USDA hardiness zone.
