A world of plants under glass
Warm house with tropical plants
In a show greenhouse, 800 species of Central and South American wild plants and useful plants from all tropical regions of the world grow on an area of 500 square metres.
The collection of useful plants is particularly worth seeing, with around 100 varieties on permanent display. In addition to "commonplace plants" such as pineapples, bananas and coffee bushes, you can also see cola trees, rattan palms and taro. Well-known foodstuffs such as millet, rice and manioc also thrive here.
Many exotic plants that have long been part of our daily lives can be marvelled at in the show greenhouse. Visitors can see how papayas and annonas grow, as well as spices such as chilli, cardamom, pepper and vanilla.
Cold house with Mediterranean plants
This part of the greenhouse contains a small selection from the great wealth of species in the Mediterranean region: particularly decorative wild plants such as rock roses and viper's bugloss species, rosemary and oleander. The majority of the 100 or so plant species here are also useful plants. In addition to Mediterranean species such as cork oak, olive and lavender, subtropical useful plants from all over the world such as oranges, tea, Japanese loquat and sisal agaves are on display.
Tropical and subtropical orchids, which are too warm in the neighbouring tropical house, are displayed in a showcase. There is also a small collection of carnivorous plants, including sundew, butterwort, tubular leaf and the Venus flytrap.
Cacti and succulents
The 120 square metre facility is divided into two areas.
Cacti and succulents, mainly from Mexico, are displayed in the centre of the house.
In the outer areas of the greenhouse, succulents from southern Africa and Madagascar can be seen. This allows visitors to observe how different plant families adapt in a similar way to the same site conditions (convergence).
It is worth comparing columnar cacti with columnar spurge or agaves with aloes.
