Out of 165 scientific papers, a staggering 120 found native species consistently outperform non-native plants in supporting local ecosystems and providing environmental benefits. This systematic review reveals a clear ecological advantage for indigenous flora in maintaining robust local biodiversity. Homeowners aiming for sustainable landscaping must consider this scientific consensus.

Despite the review's findings, some horticulturalists assert non-native plants are more successful, providing equal or greater habitat and ecosystem services. This assertion creates a tension between traditional gardening practices and ecological research, exposing a significant divide between practical belief and scientific evidence. Such choices often inadvertently undermine local ecosystems.

Homeowners seeking to maximize environmental benefits and biodiversity will increasingly adopt native plant-focused landscaping. This will shift mainstream horticultural practices towards ecological functionality over purely aesthetic considerations, prioritizing long-term ecological health and fostering more resilient residential environments.

Sustainable landscaping designs outdoor spaces to be environmentally responsible, resource-efficient, and supportive of local ecology. This goes beyond water reduction, focusing on plants that naturally thrive locally, minimizing fertilizers and pesticides. A core principle enhances biodiversity by creating habitats for local wildlife: insects, birds, and small mammals.

This contrasts with conventional landscaping, which prioritizes ornamental aesthetics without ecological impact. Traditional methods often rely on non-native species, heavy irrigation, and chemical treatments. Sustainable landscaping integrates the garden into the natural environment, fostering a self-sustaining system that considers soil health, water conservation, and overall ecological footprint. The shift emphasizes native plants, naturally adapted to local climates, requiring less water and maintenance. Their evolutionary history with local fauna provides specific food and shelter, forming crucial links in the local food web.

The Ecological Imperative: Why Native Plants Win

A systematic literature review, using PRISMA methodology, assessed native and non-native plants in urban green spaces, focusing on faunal biodiversity, ecosystem services, and plant performance. Out of 165 papers, 120 found native plants consistently outperform non-natives on these metrics, according to plant native: comparing biodiversity benefits, ecosystem services, and plant performance. This overwhelming scientific consensus challenges long-held horticultural beliefs, providing a clear foundation for sound landscaping decisions.
