Ornamental horticulture is the science, art, and technology focused on the cultivation, management, and utilization of plants primarily for aesthetic, amenity, and environmental purposes. As an academic and research field, it investigates the biological principles, genetic improvement, propagation methods, cultural practices, and ecological interactions pertinent to ornamental plant species. Key characteristics include its interdisciplinary integration of plant science, landscape design, and environmental studies, aiming to enhance human environments and well-being. Its significance lies in contributing to urban greening, biodiversity conservation, economic development, and the creation of functional and beautiful landscapes.
