This “conservation” greenhouse is home to some rare and endangered species. The greenhouse is a good illustration of the botanical garden’s key role in preserving species in danger. Most of the plants grown here come from the Indian Ocean islands: the Seychelles, Mauritius, Reunion Island and Rodrigues.
In the imposing section dedicated to Reunion Island is one of the last examples of Saribus jeanneneyi, one of the rarest palm trees in the world. Other unusual palms are also presented, such as Dypsis decaryi, known as the triangle palm, the hurricane palm Dictyosperma album, and the bottle palm, Hyophorbe lagenicaulis.
Rarities such as Obetia ficifolia and Hibiscus liliflorus, which no longer exist in nature, are kept here.
Visitors will also be impressed by the foliage of the iconic traveller’s tree, the stilt-like roots of the Pandanus and the impressive arborescent ferns from Australia.
