Conservatoire et Jardin botaniques de la Ville de Genève
The Exhibition Greenhouse
This greenhouse, renovated in 1987, is devoted to wild indigenous plant species rather than domesticated and cultivated ones. Its climate is identical to that of the Winter Garden, but its tropical nature is accentuated by the profusion of epiphytic plants. Two large and entirely artificial trees have been designed specifically for the epiphytic plants (which use trees for support and not as parasites). They are made of stainless steel that is covered in the cork from cork oaks which gives these artificial trees a rustic and decorative appearance. Various species belonging to the families of orchids, Bromeliaceae, ferns and the Gesneriaceae are cultivated here. Rhipsalis, which belongs to the Cactaceae but lacks spines, also prosper well there.
The scenery created in the greenhouse comprises a waterfall made of pink Bourgogne granite with a pond to accommodate different aquatic and floating plants. A most impressive giant Waterlily from the Amazon (Victoria cruziana) is found here and you are able to look at it from a small pavilion. After observing the wall of greenery that is made up of some climbing Araceae and some rare palms that shelter numerous Calathea, one can choose between a visit to the rockery scenery in the greenhouse of Bromeliads (a family of Latin American origin to which the Pineapple, seen in the Winter Garden, belongs) or a visit to the greenhouse for the Gesneriaceae, the family to which the Saintpaulia (African violet) belongs and with which you may be familiar. This greenhouse is employed by botanists to follow certain plants and exhibit some aspects of their scientific research. The adjoining greenhouse for carnivorous plants and succulents can be visited upon request (to the gardeners responsible).
