The new Tropical Montane Orchidetum at Singapore Botanic Gardens showcases the most diversity of orchids found in tropical montane forests, in a single location in Singapore. It comprises three display houses – The Sembcorp Cool House, Tan Hoon Siang Mist House, Yuen Peng McNeice Bromeliad Collection, as well as the surrounding outdoor display areas that showcase lowland forest and stream habitats, and a Secret Ravine that emulates habitats that can be found in deep, narrow valleys of tropical mountains. The Sembcorp Cool House in particular, features the largest collection of high elevation montane orchids in Asia.

Designed in a way that allows visitors to see the orchid species and varieties set amid naturalistic landscapes resembling the habitats where they are typically found, the Orchidetum also plays an important role in the ex-situ conservation of these increasingly endangered orchids, as researchers will now be able to study at close range, rare orchids that would otherwise only be found naturally at higher elevations in other countries.

Visitors will be able to enjoy a seamless experience akin to that of one ascending a tropical montane forest as they make their way through the Orchidetum. Each of the display houses within the Orchidetum has been expanded beyond their original size, increasing by almost threefold the combined display area.
