Arboretum Nový Dvůr, Botanical garden in Stěbořice, Czech Republic.

Arboretum Nový Dvůr is a botanical collection in Stěbořice that brings together plants from different regions around the world. The grounds include extensive garden areas where visitors can walk through sections featuring specimens adapted to various climates.

Quido Riedel (1878–1946) created a landscape park on 1.8 ha at Nový Dvůr between 1906 and 1928, growing some 500 species and cultivars. He left in 1928 for Bílá Lhota, and his daughter Alžběta Schubertová and her husband Walter kept the park until 1945 without adding to it. After postwar neglect it passed to the Silesian Museum in Opava in 1958, which founded the arboretum and enlarged it to 23 ha.

The name Nový Dvůr refers to the estate whose manor houses stood here; the older one, built by Ludvík Klettenhof before 1836, was demolished around 1965/66, and only the western and southern farm buildings and the old tree-lined avenue to the courtyard survive. The newer manor house was built by Baron Antonín Luft.

The grounds are best explored on foot, with paths that lead through different garden areas. The best time to visit is during the warmer months, when plants are in full growth.

At the heart of the grounds sits a heated greenhouse that recreates tropical conditions and offers visitors an unexpected look at plant life from warmer continents. This separate area lets people see species that could not survive in the open garden.
