Ornamental Horticulture is a specialized branch of horticulture that deals with the commercial cultivation of ornamental plants and the enhancement of the aesthetic appeal of the surrounding environment. It plays a crucial role in improving the overall environment and combating visual pollution through the use of ornamental plants. Flowers, in particular, have been admired by poets and artists for generations not only for their beauty but also for their medicinal properties.The study of ornamental horticulture encompasses two aspects: the cultivation of a wide variety of plants, including annuals, shrubs, climbers, trees, bulbous plants, succulents, cacti, shade-loving plants, and lawns, and their application in beautification programs. However, information on these topics is scattered across different books, making it difficult for students, landscape designers, and scientists to access.
