The greenhouse complex alongside the railway track
This complex consists of several compartments, most of which can be visited. The biggest of them house a spectacular range of tropical plants, principally palms and aquatic plants. Their arrangement was conceived to trace the evolution of the plant world, going from the algae in the aquarium, following through to the ferns and other flower-less plants, the Cycads, the palms, the Araceae, etc. Numerous epiphytic plants may be found growing on artificial trees that are covered with layers of cork.
A large pond allows Victoria cruziana to easily spread out its huge leaves. In effect, this annual water-lily, originating from South America, is one of the biggest on the planet.
The three adjoining compartments hold collections by theme:
The water used for watering the greenhouses is principally rainwater that is obtained from the roofs of the greenhouses and the “maison des jardiniers.” It is collected in two cisterns situated underneath the greenhouses that hold about 1000 cubic metres. An installation for demineralisation by inverse osmosis is used when there is little or not rainfall. The water is warmed to 77° F (25°C).
