The Singapore Supertrees are tree-like structures that dominate the local landscape with varying heights that are from 25 metres (82 ft) and 50 metres (160 ft) tall. They are vertical gardens that perform a multitude of functions, which include planting, shading and working as environmental engines for the gardens.
The man-made mechanical forest consists of 18 supertrees that act as vertical gardens, generating solar power, acting as air venting ducts for nearby conservatories, and collecting rainwater. To generate electricity, 11 of the supertrees are fitted with solar photovoltaic systems that convert sunlight into energy, which provides lighting and aids water technology within the conservatories below. 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 breathtaking aerial view of the Gardens. A food and beverage outlet is planned atop the 50-metre (160 ft) Supertree. At night, the Supertrees come alive with a light and music show called the OCBC Garden Rhapsody.
