The Botanische Gärten der Friedrich-Wilhelms-Universität Bonn (6.5 hectares open to public, 3 hectares private), also known as the Botanischer Garten Bonn, is a
botanical garden and
arboretum maintained by the
University of Bonn. It is located at Meckenheimer Allee 171,
Bonn,
North Rhine-Westphalia,
Germany, and open except Saturdays in the warmer months; admission is free on weekdays.
The gardens were originally castle grounds for the Archbishop of Cologne, dating to about 1340, which circa 1650 were fashioned into a Renaissance garden. In 1720, the site was reworked as a
Baroque garden, setting the basic structure of today's garden, with the rococo
Poppelsdorf Palace completed in 1746 by Archbishop Clemens August. When the University of Bonn was founded in 1818, its first garden director, Dr.
Christian Gottfried Daniel Nees von Esenbeck (1776-1858), began to focus the garden on scientific
botany. By 1900 the garden was second only to
Berlin's within Germany, but it was utterly destroyed in
World War II. Reconstruction began after the war and was completed in 1979-1984 with the construction of two conservatories.
Today the garden cultivates about 8,000 plant
species, ranging from endangered local species from the
Rhineland such as Lady's Slipper Orchids to protected species such as Sophora toromiro from
Easter Island. Its outdoor gardens, containing about 3,000 species, are organized as follows:
Geographical section - plants grouped by geographical origin.
Biotope section - the most important locally occurring plant communities, including
endangered species from the Bonn region.
The garden also contains about 0.5 hectares of
greenhouse area, including a major conservatory (2,500 m²) completed in 1984. Roughly 3,000 species are cultivated in public areas as follows:
Fern house -
tree ferns and other indigenous plants from cool cloud forests on tropical mountains.
