Gardens by the Bay will have conservatories that will bring in plants native to more temperate climates as well as themed gardens that explore the different cultural traditions that make up Singapore. And drawing attention to these are 18 giant steel and concrete trees, between 25 m to 50 m high. These Supertrees, as they are called, consist of concrete trunks with a canopy made of a complex of steel tubes that form the branches at the top of each tree. The tops of some of the trees will have solar cells that will generate power for use in the conservatories below. The trunks of the Supertrees are similarly clad in a steel frame and draped with many types of climbers, flowers and ferns.
