The Botanischer Garten der Universität Heidelberg (2 hectares), also known as the Botanischer Garten Heidelberg, is a botanical garden maintained by the University of Heidelberg. It is located at Im Neuenheimer Feld 340, Heidelberg, Baden-Württemberg, Germany; portions are open to the public daily except Saturday without charge.
The garden was established in 1593 as a hortus medicus for the University of Heidelberg. As such, it is the third oldest botanical garden in Germany, but has moved seven times since its establishment. The present site was created in 1915 by Georg Albrecht Klebs and head gardner Erich Behnick. It was severely damaged in World War II but has subsequently been rebuilt.
Today the garden contains over 14,000 plant taxa, with a primary focus on its greenhouse collections (4000 m² total area), with strengths in succulents, orchids, and bromeliads. The following 11 special collections form its core holdings:
The garden's outdoor sections contains plants from bogs and heath, an alpine garden, fern ravine and inland dune, weedy vineyard, and a systematic collection. The herbarium contains over 250,000 specimens representing more than 50,000 taxa.
