The Garden's Outside Area - Hardy Plants

Owing to the area’s atlantic, mild climate, around 3,000 species of plants from temperate zones of the world can be cultivated outside at Bonn Botanic Gardens.

In the Arboretum (collection of woody plants), there is a large specimen of the monkey puzzle tree (Araucaria araucana), stinking cedar (Torreya), tupelo tree (Nyssa) and Chinese pine (Pinus bungeana), which is especially striking due to its multicoloured bark; and there are old specimens of swamp cypress (Taxodium distichum) from the Everglades in Florida. One curiosity is a ginkgo (Ginkgo biloba) with male branches grafted onto it.

In the Systematic Section, plant relationships of around 1,200 different species are presented; ‘order in diversity‘ is the overriding subject. Hemp palms (Trachycarpus fortunei), passion flower (Passiflora caerulea) and Californian laurel (Umbellularia californica) can be found here, to name but a few. A stroll through this department helps you to spot plant relationships and lets you divine the paths that the evolution of flowering plants took.

In the Geographical Section around the palace, plants are grouped according to their geographical origin. Summer is the best time to visit this part of the garden.

The Biotope Section shows the most important locally occurring plant communities. Endangered species of the region around Bonn are on display.
