Singapore successfully improved the appearance of the sterile, urban Marina Bay landscape by constructing the Garden by the Bay. The 250-acre self-sustaining oasis opened in June. Singapore’s National Parks Board developed the site, which celebrates culture and horticulture through various exhibits that include the phenomenal Singapore Supertrees.


The southern region of the Bay garden features 18 structures that combine the technology of human ingenuity with Mother Nature in a dazzling display known as the Supertrees. Each steel encapsulated concrete structure resembles something akin to a bare winter’s tree or the framework of an umbrella. The artificial trees stand anywhere from 25 to 50 meters (82 to 164 feet) tall. The man-made trunks bear steel mesh that serves as a vertical garden space and provides a home for a variety of live greenery and tropical plants.

The Supertrees also collect rainwater and house air vent ducting connected to nearby conservatories. Eleven of the trees contain solar voltaic systems, which provide the power for LED lighting that illuminates the array at night. The solar electricity additionally powers the water conserving technology contained in an underground irrigation system. Branchlike framework at the top of the trees provides shade. The branches also moderate the temperature of the growing plants by absorbing and radiating heat.

Aerial bridges, known locally as skywalks, connect several of the largest trees at heights of 20 to 25 meters (66 to 82 feet) above ground and provide pedestrians with the opportunity of gaining a bird’s eye view of the garden below. One of the taller trees also features a bistro for the convenience of spectators.

Green Conservatories

The expansive gardens also feature two green conservatories called the Cloud Forest and the Flower Dome. Encompassing the space of four football fields, the climate-controlled biodomes resemble the shape of orchids and house over 200,000 plants from around the world. Temperatures within these synthetic structures remain a constant 23 degrees Celsius (73 degrees Fahrenheit) during the day and lower to between 10 to 13 degrees Centigrade (50 to 55 degrees Fahrenheit) at night. Horticultural experts explain that the cooler temperatures encourage blooming.

The unbelievable selection of plants occupying the vast spaces includes species found in deserts, Mediterranean and sub-tropic regions. A central area contains elaborate floral displays that change every four to six weeks. Waste collected from the self-sustaining Flower Dome powers a massive steam turbine, which helps generate electricity for the garden and controls the internal climate.

Celebration of Cultures

The Supertrees and biomes comprise only a small fraction of the gardens. Project designers additionally developed a sizable cultural exhibit on the remainder of the land. The Heritage Gardens commemorate Singapore’s history and the cultures and histories of the many people. Cultures represented in the exhibits include the many Chinese, Indian and Malaysian residents.

Separated into various themes, plants in one area represent the herbs popularized by Chinese medicine while another area contains coconut trees and other tropical flora associated with Malay. A plant and planet exhibit explains the significant role plants play on the planet. One biome features a rainforest complete with orchids, mosses and other plant species commonly found in Indonesia and Malaysia. The spacious setting also has a 35-meter (115 foot) cascading waterfall.

Surrounding the Supertrees, biomes and Heritage Gardens landscaping includes vast sprawling lawns decorated with shrubbery and forested areas. Various bridges and lakes connect and divide different spaces of the garden. The Garden by the Bay also features beverage and food outlets dispersed throughout the location.
