Louisiana Native Plants

A plant is considered native if it has occurred naturally in a particular region or ecosystem without human introduction. There are many benefits to growing native plants. First, these plants are better adapted to soils, moisture, and weather than exotic plants that evolved in other parts of the world. They need fewer fertilizers, and pesticides or use less water. Second, they are unlikely to escape and become invasive, destroying natural habitats. Third, they support wildlife, providing shelter and food for native birds and insects, while exotic plants do not.
