This document discusses the benefits of using native plants in home landscaping. It begins by explaining that while early American gardens featured European styles and exotic plants, some advocates promoted using native species. It then defines native, non-native, and invasive plants. The summary discusses how native plant landscaping provides ecological benefits like supporting wildlife, requires less maintenance, and helps the local environment. It concludes by offering tips for homeowners to begin incorporating native species into their existing landscapes or when planning new designs.
