The Botanical Garden Chotobuz was founded on the 1st January 1963. From its beginning, it has focused on collections for studying and expositional purposes, that register the development of breeding selected barren plants, their variability and the preservation of gene pools. Until 1990, the garden was closed to the public and was used only for gene pool reservation and research. In 1994, it was opened to the public as an architectural expositional garden (area of 3,5 hectares).There visitors can see expositions dedicated to individual families in a representative selection. Visitors can also see a selection of the most intruiging garden varieties of water lilies (Nymphaea).
