History
The arboretum was founded around 1811 when the owners of the Wojsławice village - von Prittwitz and von Aulock families started planting the first trees of non-European origin (mostly North American). The current design of the arboretum was created by Fritz von Oheimb in 1880 (commemorated by the Fritz Pond in the Arboretum), a Silesian landlord and a keen plant lover. He became an owner of 150 ha (370 acre) property in Wojsławice, with a romantic park created in 1821 by von Aulock family. Alongside his wife – Bertha von Oheimb - he began remodeling of the park, constantly acquiring new plant species. Since the beginning of twentieth century, rhododendron plants became his main specialization. In 1920 collection consisted of about 300 varieties. In 1890 Fritz donated them to the Botanical Garden in Wrocław. Fritz von Oheimb died on 11 October 1928 at the age of 78. He was buried within the grounds of the park. Until 1946 his passion was continued by his son – German geologist and botanist - Arno von Oheimb. In year 1906 as a recognition of Fritz's work, German rhododendron breeder Traugott Jacob Rudolf Seidel has named one of this late-blooming Rhododendron catawbiense hybrids ‘Von Oheimb Woislowitz’.

In 1983 park became a historical site and since 1988 it is a branch of University of Wrocław.

In 2005 a new 54 ha (99 acre) grounds became attached as a new part of the park.

In 2011 collections of Rhododendron, Box and Hemerocallis were accredited by Polish Dendrological Society as a National Collections

Since 2013 Arboretum Wojsławice is accredited as a display garden of American Hemerocallis Society. Year later it became a European Station for Hemerocallis Evaluation

In 2017 the GEOretum has been opened. At the site of the local quarry a permanent exhibition of various Lower Silesian rocks is being presented

2020 was a year when a Polish Millennial Garden was officially opened for a public display.
