Calocedrus decurrens
The arboretum was established in 1871 by Christian Friedrich Gustav Freiherr von Berckheim (1817–1889), former Minister of State and Großhofmeister at the court in Karlsruhe, on the grounds of a baroque estate founded in 1725. His initial plantings were extensive – between 1872–1883 he planted some 12,494 trees on 36 hectares – with specimens purchased predominantly from specialist nurseries in Orléans, Ghent, and Exeter. Approximately 1460 sequoia trees were planted in this interval within a 2 hectare site. Although the climate has not proved entirely hospitable, and the original catalog of 150 species has subsequently dwindled to about 50, many mature specimens still remain, including original plantings of "Calocedrus decurrens", "Sequoiadendron giganteum", "Pinus jeffreyi", "Pinus ponderosa", and "Thuja plicata".
