In March and April, when the first flower buds open in the open air of the Botanical Garden, it is already peak bloom in the Alpine House.
The small show house, which allows visitors:inside to look in from the outside, is divided in two and consists of a smaller, frost-free section and a larger, completely unheated part. Thus, frost-sensitive plant species as well as species from mountainous regions with little rainfall can be cultivated.
On the table beds, the permanent planting of dwarf shrubs and small perennials is arranged in such a way that bays are left free between them. Currently flowering bulbous and cushion plants are displayed in these places, which come from the extensive pot collection behind the scenes. In addition to the outdoor cultures in the Alpinum and the Alpine Garden on the Schachen, the Alpine House is the third important support for the focal collection of alpine plants.
