The Botanical Garden of the University of Bonn is a historic botanical garden founded in 1818. It is located in the Poppelsdorf district of Bonn, Germany, and covers an area of around 16 hectares. The garden is home to over 10,000 species of plants, including a large collection of tropical and subtropical plants, and serves as a research and teaching center for the University of Bonn's Department of Biology.
