The oldest surviving botanic garden in Germany emerged from the palace park, owned by local Landgrave Ludwig V. In 1609 he presented part of his property to the University opened in Giessen, which was used to grow an apothecary garden. By the end of the XVIII century, the territory of the garden turned into a botanical garden. It is not much different from hundreds of its counterparts in the world: trees, shrubs and flowers (over 7,500 species) of different continents and climatic zones, statues of researchers and a pond with water lilies. The garden was damaged during World War II and is still being restored: it is planned to restore the tropical greenhouse.
