The arboretum is part of the Silesian Museum in Opava, and includes 7,000 different species from five continents, spread over 23 hectares.

Reidl moved on to create another arboretum in 1928 but he left this collection in the care of his daughter Elisabeth.

She and her husband Walter Schubert looked after the manor houses and the collection until 1945, but they made no additions or improvements during that time.

Following the end of the war the arboretum was neglected by a series of different owners until 1958 when the Silesian Museum took control of the site, and restored the original style, consisting of both solitary and mixed groups of trees spread around open areas.

This design allows visitors to observe the different textures and shapes as they change during the seasons.
