Supertrees in Singapore are the 18 tree-like structures that dominate the Gardens’ landscape with heights that range between 25 meters and 50 meters.
They were conceived and designed by Grant Associates, with the imaginative engineering of Atelier One and Atelier Ten.
They are vertical gardens that perform a multitude of functions, which include planting, shading, and working as environmental engines for the gardens.
The Supertrees are home to enclaves of unique and exotic ferns, vines, orchids, and also a vast collection of bromeliads such as Tillandsia, amongst other plants.
They are fitted with environmental technologies that mimic the ecological function of trees: photovoltaic cells that harness solar energy which can be used for some of the functions of the Supertrees, similar to how trees photosynthesize, and collection of rainwater for use in irrigation and fountain displays, similar to how trees absorb rainwater for growth.
The Supertrees also serve air intake and exhaust functions as part of the conservatories’ cooling systems.
There is an elevated walkway, the OCBC Skyway, between two of the larger Supertrees for visitors to enjoy a panoramic aerial view of the Gardens.
Every night, at 7:45pm and 8:45pm, the Supertree Grove comes alive with a coordinated light and music show known as the Garden Rhapsody.
The accompanying music to the show changes every month or so, with certain themes such as A World of Wonder and A Night of Musical Theatre, which features excerpts/pieces from films like Jurassic Park and Pirates of the Caribbean.
There is also a newly opened attraction called the Supertree Observatory, which opened on 27 December 2019.
This attraction is housed inside the tallest Supertree which is 50 metres tall.
It comprises 3 levels, the ground floor, the Observatory Space and the Open-Air Rooftop Deck.
Visitors would take the lift up to the Observatory Space and thereafter take a flight of stairs up to the Rooftop Deck.
The Observatory Space is located one level below the rooftop deck and it consists of an indoor area with full-height glass windows, as well as a peripheral outdoor walkway.
Here, visitors can also experience a message about the effects of climate change creatively conveyed through digital media.
The Open-Air Rooftop Deck, which is an open-air observation deck on the canopy of this Supertree, offers 360-degree unblocked views of the Gardens and the Marina Bay area.
Italy’s Pavilion in Expo 2015, featured a structure called Albero Della Vita (or “Tree of Life” in Italian), which proved visually similar to Singapore’s Supertrees.
