A wide variety of multi-stemmed trees at about eight metres above ground level form a natural contrast to the industrial look of the Inspyrium.
Visual experience and edibility
The roof garden features a variety of multi-stemmed trees and shrubs, islands of perennials, fruit trees, herbs and façade greenery. It is a varied, organic landscape with cosy seating areas, a greenhouse, a pergola and a bar, as well as floating dining chairs at a floating table and 3D printed benches. There is also a windmill that automatically refills the birds' drinking bowl by means of an overflow, a large bird's nest and bird boxes from a bird working group. The gigantic tree house with a beautiful view over the landscape and the roof garden completes the picture. A strip of characterful trees with compound leaves and underplanting with mainly large-leaved shrubs/plants and many ferns provide a jungle feel at the tree house.
For the plant lover, the assortment is special. A wealth of species and biodiversity, in all seasons. The 'jungle trees' have edible fruit in most cases, and trees giving edible fruit have also been used in the islands. The underplanting of herbs such as dwarf origanum, hyssop, savory, creeping thyme, wild garlic, sage and mint complements this.
At the back of the roof garden, an acid-loving corner has been set up. Here, lime-rich lava substrate has not been applied, but more acidic roof garden substrate with peat. Blueberry, cranberry, honeyberry, foxberry, mountain tea and goji berry do very well here.
