Parma’s Botanical Gardens hold many varieties of plants and flowers which belong to different and wide-ranging environments. The botanical garden is a popular place with visitors as well as natural history students. It is maintained by the University of Parma and succeeds the city’s earlier Orto dei Semplici, a garden for medicinal plants, established by Ranuccio I Farnese, Duke of Parma. This garden was created in 1770 by Giambattista Guatteri under the sponsorship of Ferdinand I and the glass house was completed in 1793. There is no charge to visit.
