The Botanical Garden was founded on January 1, 2002. However, it was not created “on a greenfield site”, but its area has been used for horticultural purposes for around 100 years. Little is known about the garden's beginnings at the end of the 19th century. Count Clary-Aldringen may have played an important role, but it is also possible that this is just a rumor. What is certain is that the word Stadtgärtnerei can be found on the building plans from 1904. Among the unique plant species to be seen in the garden are an ancient specimen of the African conifer Afrocarpus (Podocarpus) gracilior or the cycad Encephalartos villosus from the same area, a huge specimen of the Philippine Medinilla magnifica, the beautiful Mexican Dasylirion serratifolium or fifty-year-old cacti and other succulents from the collections of Professor F. Eck and above all the Teplice cactus grower V. Pulce. Also worth mentioning are two seventy-year-old, richly fruiting specimens of Gymnocladus canadensis.
