Using native plants in landscaping offers significant advantages, particularly their adaptability to local conditions and lower maintenance requirements. Native plants have evolved over time in their specific ecosystems, which means they are well-suited to the climate, soil types, and typical pests or diseases found in that area. This inherent compatibility allows them to thrive with less intervention from gardeners, such as reduced watering, fertilization, and pest management efforts.

This adaptability often results in healthier plants that establish themselves more easily, leading to a landscape that is both beautiful and resilient. Additionally, native plants provide vital habitats and food sources for local wildlife, further enhancing the ecological health of the area.

While cost, growth rate, and color are important factors in plant selection, the key benefit of using native species lies in their suitability and sustainability within the local environment, making choice B the most compelling reason.
