Düsseldorf Botanical Garden, Botanical garden at Heinrich Heine University, Düsseldorf, Germany.

Düsseldorf Botanical Garden is a green space on the campus of Heinrich Heine University, displaying plant species from a wide range of climate zones around the world. The grounds are divided into geographic sections that visitors can walk through on foot, showing how plants grow in their native regions.

The garden was founded in 1974 alongside Heinrich Heine University and was planned from the start as a scientific facility. Its original role as a teaching and research space still shapes how it is organized and how plants are presented to this day.

The garden is run by the Institute of Botany of Heinrich Heine University, and its plantings serve teaching there: outdoor beds are grouped by geography, ecology and systematic botany, and ecological and sociological studies on the grounds feed into diploma, examination and doctoral theses. The garden also takes part in the Index Seminum, exchanging seeds free of charge with other botanical gardens and university institutes.

The garden is at Universitätsstraße 1 in the south of Düsseldorf, on the Himmelgeister Rheinbogen, and is open daily in the warmer months with free admission. The outdoor grounds cover 8 hectares, so allow time to cross from the geographic beds to the central dome, the orangery and the South Africa house. The dome greenhouse stays at 12–15 °C in winter.

One of the more unexpected features of the garden is a dome greenhouse standing 18 meters tall that houses plants from the Mediterranean region and the Canary Islands. The climate inside is carefully controlled year-round, which means visitors can experience Mediterranean and subtropical species even outside their natural season.
