Drought-tolerant plants are species that can survive with minimal water. They have adapted to arid environments by developing features such as deep root systems, thick leaves, and waxy coatings that reduce water loss. Common examples include succulents, cacti, and certain types of grasses. These plants are ideal for gardens in dry climates or areas with limited rainfall. By choosing drought-tolerant varieties, gardeners can conserve water and reduce maintenance efforts. Additionally, these plants often require less fertilizer and are more resilient to pests, making them a sustainable choice for landscaping.
