This giant nursery outside Antananarivo is mainly about Madagascar orchids and caudiciforms. Several shadow- and greenhouses houses a great collection of very interesting plants. All the buildings are brand new, and the plants are very well looked after. Beside from all the small seedlings (i.e. 20,000 Pachypodium of various  species), there are some huge mother plants. I visited in 2006.
