Ornamental Plants, which have a different place among plant groups, have started to take their deserved place in our lives. The ornamental plants we use to soften the increasingly stressful living conditions, except for their cultivation and benefit in food, textile, medicine, cosmetics, industry fields, bring us closer to nature, especially in this technological-digital age. In fact, we can say that there are many unknown aspects of these beautiful ornamental plants that we see at home and indoors, on our balconies, parks and gardens, and they touch us in areas we have never known in our lives. In this book, these areas are tried to be addressed from different ways. These studies cover the botanical and phenological characteristics of some ornamental plants, their phyto-chemical content, ecological characteristics, fertilization, disease-pest-weed control, growing conditions, production techniques, usage areas, health benefits and the place of this sector in our country.
