What does "drought-resistant" mean in landscaping?

"Drought-resistant" in landscaping refers to plants that are capable of thriving with minimal water, typically adapted to arid conditions. These plants have developed various physiological and morphological traits that enable them to conserve water and withstand prolonged periods of dryness. Such adaptations may include deep root systems to access moisture, waxy leaves to reduce water loss, or the ability to go dormant during dry periods and flourish when water becomes available again. These characteristics make them especially valuable in landscaping, as they require less maintenance and can help conserve water resources in gardens and public spaces, particularly in regions prone to drought.

The other options do not accurately define "drought-resistant." Some suggest the opposite characteristics, such as requiring frequent watering or thriving only in fertile soils, which does not align with the essence of drought resistance. Thus, understanding the definition of drought-resistant plants is crucial for effective landscaping in varying environmental conditions.
