Botanischer Obstgarten Heilbronn, Botanical garden with fruit trees in Heilbronn, Germany.

Botanischer Obstgarten Heilbronn covers 1.7 hectares on Im Breitenloch street at the foot of the Wartberg, next to Heilbronn's Jewish cemetery. It combines an arboretum of regional fruit trees and berry shrubs with display and school gardens, plus 14 historic garden houses and arbours moved here and restored. Old boundary stones, well troughs and a stone cross stand among the plantings.

In 1859 Heilbronn citizens founded a work institution for boys, which moved to this site in 1900 and combined school lessons with practical work in crafts and horticulture, following Johann Heinrich Pestalozzi's ideas; Heilbronn was the first German city to apply this method. After the association dissolved in 1934 the grounds served as a municipal fruit farm, from 1965 as a tree nursery. In 1998 the city council resolved to create the botanical fruit garden, opened around 2000.

The name Obstgarten refers to the orchard of regional fruit trees and berry shrubs, laid out as Streuobstwiesen like those of the southern German countryside. Pruning courses and guided tours teach visitors how to care for fruit trees. The Schulgarten, where pupils grow potatoes, maize, tomatoes and courgettes, continues the site's link with the Pestalozzi school.

The garden lies on Im Breitenloch street at the foot of the Wartberg, next to Heilbronn's Jewish cemetery. Entry is free and the grounds are open during the day all year round. The main entrance is in the western section, where the cut-flower field for the farm shop is planted; the show gardens and most flower beds lie in the eastern half.

The oldest building in the collection is a vineyard hut from Schwäbisch Hall, datable by its interior wall paintings to around 1530, though it was built from even older timber. The 14 garden houses and arbours were moved here from their original sites and restored; their builders ranged from wealthy burghers to small allotment gardeners.
