Botanical Garden

The cold house differs from other greenhouses in that it houses potted plants that change their location during the year.

Winter half year: When the temperatures inside are cool but not cold, numerous larger potted plants that spend their summer outside are brought in over winter. Most of these are cold-sensitive, Mediterranean plants. The display cases also show exceptionally colorful bulbous plants from the southern hemisphere, mainly from South Africa, which bloom during our winter.

Summer half year: In summer, the greenhouse climate is changed to a warm tropical climate with 28° C and high humidity. Then, numerous Amorphophallus species bloom. These hibernate from September to April in a leafless state, in warm and dry conditions.
