Gardens By the Bay is Singapore's version of Eden.
They have delicate plants called super trees and they are growing vertically in a frame made of steel and concrete. Creators say the goal is to attract people who don't usually visit gardens.
"And so you have to wow them first. Bring them in and say beneath all that wow, there is a very serious message of biodiversity and sustainability," said Kiat Tan, CEO of Gardens By the Bay.
The ambitious project will be finished next year.
