Ornamental Plants are plants that affect both the eye and the soul, and are always present in our lives with their unknown aspects. We love and use some of them for the color of their leaves changing according to the seasons, some for its distinctive visual stem, some for its fragrant and colorful flowers, some for its refreshing body and other ingredients that concern our health. We have always had contact with these plants without realizing it. Because we are always intertwined with ornamental plants in daily life, especially in landscaping. As in every subject, new research results are revealed and continuous information updates are also made in ornamental plants every day, and as a result, different perspectives are brought to applications and subjects. In this book, there are studies that give information about the growing techniques of ornamental plants and especially their use in landscape. For this reason, I would like to express my special thanks to our valuable authors who shared their research with us in the creation of our book.
