The first botanical gardens of the 16th and 17th centuries contained mostly medicinal plants—a kind of apothecary of sorts—, but contemporary gardens offer a variety of themes, showing off plants that thrive in many different ecosystems. With plant diversity on a sharp decline, botanical gardens are proving to be more important than ever. They devote their resources to the study and conservation of plants, while also teaching the public about biodiversity and inspiring environmentalism. Plus, they offer beautiful scenery—often in the midst of crowded cities—that all nature lovers can appreciate. Learn more about 15 of the most beautiful botanical gardens in the country and be sure to add them to your must-visit list. 1 of 15 Desert Botanical Garden iShootPhotosLLC / Getty Images The Desert Botanical Garden in Phoenix, Arizona, is a magnificent retreat full of cacti, succulents, and other desert flora.
