Landesarboretum Baden-Württemberg, Botanical garden and arboretum in Hohenheim, Stuttgart, Germany

The Landesarboretum is a botanical garden and tree museum spread across spacious grounds in Hohenheim, displaying thousands of different tree species from around the world. The collection includes deciduous and coniferous trees arranged in different sections by plant family or geographic origin.

Duke Carl Eugen of Württemberg laid out the English landscape park southwest of Schloss Hohenheim between 1776 and 1793, with a first tree register drawn up in 1779. Two collections were planted: a garden of Württemberg plants and an American garden of North American woody plants, which together held 120 species by 1783, then the richest collection of foreign trees and shrubs in Germany. After the Duke's death in 1793 the park opened to the public and most of it became an exotic state tree nursery, established for forestry research by 1797 and completed by 1813.

The garden's name comes from its status as Baden-Württemberg's state arboretum, granted in 1953. The Spielhaus, one of three surviving buildings from the founding era, houses the Museum on the History of Hohenheim. The State School of Horticulture in Stuttgart-Hohenheim uses the Exotischer Garten for training in floristry, production horticulture and landscape gardening, and guided tours are offered for adult education groups.

The arboretum lies on Garbenstrasse in Stuttgart-Hohenheim, southwest of Schloss Hohenheim, and is reached via the university campus. An online database lists every woody plant with its location, helping visitors find specimens on site. Groups and clubs can request guided tours, and adult-education courses and walks are offered regularly.

Several original trees from the 18th century still stand on the grounds today and are over 200 years old. These specimens show how the collection began generations ago and reveal the garden's long-term development.
