<p>Magnolias, renowned for their diverse botanic classification and myriad uses, are increasingly recognized not only for their aesthetic value in urban landscaping but also for their potential in pharmaceutical and cosmetic applications due to their rich bioactive metabolites. This review aims to provide a comprehensive examination of the classification, cultivation, and utility of <i>Magnolia</i> species, focusing on their integration into urban landscapes and the exploitation of their chemical properties in various industries. We delve into the existing literature to assess the cultivation practices, ecological advantages, and the sophisticated chemical profiling of magnolia metabolites. We consolidate the ecological contributions of magnolias in urban environments, emphasizing their role in enhancing biodiversity, air quality, and aesthetic appeal. Furthermore, we explore the therapeutic potential of magnolia-derived compounds, highlighting their effectiveness in anti-inflammatory, antioxidant, and neuroprotective applications and their incorporation into cosmetic products. The conclusion underscores the significant yet underexploited potential of magnolias, advocating for intensified research to harness their full spectrum of benefits. This review not only sheds light on the current status of magnolia applications but also sets the stage for future innovative uses in ecological management and biotechnological advances.</p>
