It originally formed part of the Souvan family estate in 1885, which was taken over by the University of Ljubljana in 1952 and legally declared a place of cultural and natural heritage of national importance.
Now independent of the university, it is the most visited botanical garden in Slovenia and in recent years has become well known for its spring flower shows.
His son Leon Souvan enlarged the park by pulling down the walls and planted around 12 hectares with domestic and exotic trees.
The original entrance tree avenue from the 19th century is continuous with the central part of the park and is geometrically formed in a French style.
The park includes five artificial lakes and 30 hectares of forest, which houses a particularly important union of fir and three-lobed moss (Bazzania trilobata).
Trees and bushes belong to the basic botanical species from Europe, North America, and Asia as well as to cultivars that have been raised for ornamental purposes.
The park gallery, renovated in 1991 by the architect Andrej Kemer and designer Miljenko Licul, exhibits Janez Boljka's collection of animal statues.
