  ABSTRACT: Lead (Pb) in the urban environment can have a negative effect on human health, especially children’s health. Reducing elevated Pb exposure in the home landscape is essential. The purpose of this study was to determine which ornamental groundcover landscape plants uptake Pb from contaminated soil. Plants for both shade and sun were selected. Plants for shade [Brake fern (Pteris vittata), Asian Jasmine (Trachelospermum asiaticum), “Big Blue” Liriope (Liriope muscari), and St. Augustinegrass (Stenotaphrum secundatum)] and sun [Variegated Liriope (Liriope muscari “Variegata”), Asian Jasmine (Trachelospermum asiaticum), Asparagus Fern (Asparagus setaceus), and Bermudagrass (Cynodon dactylon)] adapted landscape groundcover plants successfully assimilated Pb grown in soil containing 250 ppm and 500 ppm Pb concentrations. Additionally, soil movement at both 25 mph and 50 mph wind speed was significantly different, with increased soil movement at 50 mph. Therefore, it was determined that landscape plants adapted to both sun and shade can help remove Pb from contaminated soils and stabilize soil particles reducing the movement of soil and be aesthetically pleasing.
