Eduard Petzold is regarded as one of the most important German landscape garden art designers and theoreticians of the second half of the 19th century. He founded ‘Arboretum Muscaviense’ at Bad Muskau, which was very popular in the 19th century. His interest in dendrology was reflected in his garden designs. His garden plans included detailed plant selection guidelines. In Lower Silesia, 15 original plans survive, and so it is possible to investigate Petzold’s garden craft. This paper is aimed at raising awareness of the greenery composition principles applied by Eduard Petzold and at studying the surviving tree stands created in line with his recommendations in present-day parks.
