What is the main benefit of using native plants in landscaping?

Using native plants in landscaping offers the significant advantage of being well-adapted to the local climate and soil conditions. These plants have evolved over time alongside the specific environmental conditions of their region, which means they can thrive with minimal intervention. For example, native plants typically require less water and are more resistant to local pests and diseases compared to non-native species. This adaptability translates to lower maintenance costs and a more resilient landscape that supports local ecosystems.

The other options do not align with the benefits of using native plants. For instance, native plants generally do not require a lot of water, making them an environmentally friendly choice in terms of water use. Additionally, native plants tend to attract a diverse range of pollinators, which supports biodiversity in the area. Furthermore, the growth cycles of native plants can be variable but are often optimized for local conditions, rather than being "longer," as suggested by the option regarding growth cycles. Overall, the main benefit of native plants is their ability to smoothly integrate into and flourish within their natural environment.
