This chapter investigates the innovative integration of decorative plants in environmental remediation, examining their dual functionality in ecological restoration and aesthetic enhancement. The study covers various dimensions, encompassing the use of decorative plants in phytoremediation, their impact on soil cleanup, contributions to improving air quality, and their role in water filtration by aquatic plants. This analysis emphasizes the economic and ecological advantages of employing nonedible decorative plants for phytoremediation, including their potential to convert contaminated areas into ecotourism sites and the substantial market demand for these plants. This explores specific ornamental species acknowledged for their phytoremediation capabilities, scrutinizing their capacity to absorb, accumulate, and translocate heavy metals. A scientific examination extends to the multifaceted influences that govern remediation through ornamental plants, taking into account environmental variables like substrate composition and exposure durations. The investigation into the intricate relationship between aesthetic greenery and air quality improvement underscores the diverse mechanisms by which green spaces contribute to minimizing emissions, boosting oxygen production, and enhancing overall urban well-being. Moreover, this delves into the distinct role of decorative aquatic plants in water filtration, emphasizing their potential to address water pollution. The analysis surpasses individual plant-centric examinations, considering the interplay of environmental factors affecting water filtration. This reveals the interconnected eco-physiological dynamics that determine the efficacy of ornamental aquatic plants in contributing to cleaner and healthier aquatic environments. This interdisciplinary study bridges the gap between traditional remediation methods and visually appealing green solutions, providing a thorough understanding of the active role played by decorative plants in establishing cleaner, healthier, and more aesthetically pleasing environments. The findings strongly advocate continuously exploring and integrating decorative plants in sustainable environmental management practices.
