Invasive Shade-Tolerant Garden Plants in Georgia

Georgia's diverse landscapes, from its rich woodlands to its wetlands, face threats from invasive plants that thrive in shaded environments. These plants, while often chosen for their beauty or low maintenance, can spread rapidly and disrupt local ecosystems. By understanding these invasive species and opting for native alternatives, gardeners can help protect Georgia’s natural habitats and support ecological balance.
