Plants are cultivated for research and teaching in the experimental areas on the open-air site and in the greenhouses. The garden is involved in species conservation projects, including the cultivation of endangered species.
With its collections and the expertise of its gardeners and management, the garden serves students and researchers, various authorities such as the nature conservation authority or customs, as well as pupils from the region in the form of the Green Classroom. However, it is also open to employees of the Technical University and the general public as a place to study and relax – in keeping with the garden's motto:

He who merely smells my plant does not know it, and he who picks it merely to learn from it does not know it either.
Friedrich Hölderlin
