The Botanical Garden
The Botanical Garden not only serves research and teaching, but is also open to visitors throughout the year and offers a varied programme of exhibitions, tours and lectures. The garden’s impressive centrepiece is an 18 m tall geodesic dome. This is an over 1,000 m² cold greenhouse accommodating plant species from regions with warm, dry summers and rainy winters. Along with the characteristic vegetation of the Mediterranean and the Canary Islands, plants from Chile, Australia, New Zealand, Asia and California are on show here. The dome is supplemented by an ensemble of modern greenhouses. South African plants, particularly from the Cape region, are contained in the 335 m² greenhouse. The 13 m tall Orangery, on the other hand, is used for the wintering of potted plants and as an events space in the summer months, while the collection house has a 42 m long display frontage with changing exhibits.
The tour of the outdoor grounds takes the visitor around a roughly 3.5 ha meadow of wild flowers, on the peripheries of which summer flowers, shrubs, domesticated plants and also endangered species can be seen. The cottage and apothecary garden provides a setting for repose, while the pollination biology section calls for careful observation. The geographical section starts with North American vegetation. Via China, Japan and the Caucasus, we arrive at the plant sociology section, where the newly created moor shows typical plants of this habitat. A beekeeper has his hives in the middle of the meadow. The systematic section gives an overview of the natural kinship of flowering plants (state of knowledge in 2008), and the tour ends with a visit to the alpine landscape of limestone and granite rocks.
