Botanical Garden of the University of Vienna, Botanical garden in Landstraße district, Vienna, Austria

The Botanical Garden of the University of Vienna covers 8 hectares behind the Department of Botany and Biodiversity Research on Rennweg, next to the Belvedere gardens. Its outdoor beds are arranged partly by the APG III system and partly along the historical systems of directors Endlicher, Fenzl and Kerner, marked by the Endlicher-Fenzel-Kerner Weg opened in 2015. The 1,500 m² greenhouse complex, built 1890–1893 and rebuilt after wartime bombing, centres on a tropical house open to the public.

Empress Maria Theresa founded the garden in 1754 as a scientific facility for botanical studies. Its first director, Nikolaus von Jacquin, shaped the collections and established the location as an important research center.

The garden serves as a place where students and visitors discover plants from around the world. The carefully maintained collections showcase tropical species and rare plants that support teaching and research activities.

The grounds are easy to explore on foot, with well-marked paths through outdoor areas and covered glass structures. Visitors should be prepared for varying weather conditions, especially in the unheated outdoor zones during winter months.

In 2004, the garden received Europe's first mainland specimen of Wollemia nobilis, a plant species that was known only from fossils for many years. This specimen demonstrates how important botanical gardens are for saving and preserving extremely rare species.
