The Botanical Garden of the University of Vienna lies in Vienna’s third district, beside the Belvedere palace complex. Covering around eight hectares, it combines a historic landscape garden, scientific collections and quiet walking paths. More than 12,000 plant species from six continents grow here, including native flora, rare species and exotic plants.
History of the garden
The garden was founded in 1754 at the initiative of Empress Maria Theresa, following a proposal by her personal physician, Gerard van Swieten. It was originally created to cultivate medicinal plants and support the education of students in medicine, pharmacy and botany. Under botanist Nikolaus Joseph von Jacquin, the collections expanded and the first greenhouses were built. The grounds later grew, and plants came to be arranged according to their relationships and geographical origins.
During the nineteenth century, the garden took on the character of an English landscape park. In the twentieth century it expanded to include the former Host garden, while its greenhouses and research facilities were renovated several times. Today, it continues to support research, university teaching, biodiversity conservation and public education.
Collections and highlights
The garden displays plants from different climate zones and botanical groups. Visitors can explore collections of woody plants, alpine flora, plants native to Austrian regions, succulents and cacti, as well as areas devoted to plant evolution and diversity. The greenhouses contain specialist collections, some of which may not be open to the public.
The garden appeals to more than botanists. Winding paths, lawns and shady trees create a peaceful retreat in the city. A plant market is usually held in spring, and guided tours and educational activities take place throughout the year. Plant labels help visitors explore the collections independently.
