(CNN) -- [Updated 3:30 p.m. Monday, July 2] These man-made "supertrees" are part of Gardens by the Bay, a 250-acre landscaping project in Singapore.
Various flowers and ferns weave through the steel framework of the trees, which generate solar power, act as air venting ducts for nearby conservatories, and collect rainwater.
Organizers hope Gardens by the Bay will become a popular eco-tourist destination that showcases sustainable practices and plants from across the globe. Click here to read more about the project and see more images.
