Botanical gardens are gardens dedicated to collecting, cultivating, and displaying a wide variety of labeled plants. They contain different plant collections like tropical plants, herbs, cacti, and greenhouses. Botanical gardens are often run by universities or research organizations and serve purposes like education, scientific research, conservation, and addressing climate change by sequestering carbon and increasing cloud cover. Some examples of botanical gardens in India include the Empress Garden in Pune, Lalbagh Garden in Bangalore, and the largest in Asia, the Jawaharlal Nehru Tropical Botanical Garden in Kerala.
