One of the iconic features of the Gardens by the Bay that you will not miss is the unique towering structures known as ‘Supertrees’. They are an example of vertical gardening – home to enclaves of unique and exotic ferns, vines, orchids and also a vast collection of air plants, and perennial flowering 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 (such as lighting), 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. - Wikipedia
In the evenings there is ‘Garden Rhapsody’ - a signature light and sound show of the Gardens by the Bay where the super-trees are “transformed into a beautiful display of lights.”
People making themselves comfortable, watching the light show.
Sometime ago, I posted a video of a segment of the show. Take a look 👉 HEREif you missed that
