The Trial Garden (Sichtungsgarten)

The garden was established in 1947 and covers an area of more than five hectares. The educational and experimental garden is used to test trees and shrubs, herbaceous perennials and new varieties of rose in terms of their practical use. An important aspect of the trials is planting herbaceous perennials in aesthetically pleasing combinations in ways that suit the local conditions.

The centre of the garden is home to a variety of herbaceous perennials planted in beds and ornamental borders. On the southern facing slope, these lead into the steppe-heath (Steppenheide) vegetation typically found in Central European lowlands as well as rockeries, a pond and pool of water. The edges and western part of the garden feature a range of trees and shrubs with a rich variety of herbaceous perennials planted beneath them.

Let yourself be inspired by the garden’s diversity and the combination of herbaceous perennials, summer flowers, trees and shrubs, and discover the appeal of watching the plant arrangements change over the seasons!

The individual botanical displays invite you to reflect on which plants look attractive together. Different coloured flowers and leaves, growth habits, structures and textures are arranged so as to create beautiful garden landscapes that are either rich in contrast or harmonious. The exciting layout of the beds aims to give students and visitors inspiration for designing their own gardens.
