Next time you’re in Singapore, stop by and see the new “Supertrees” at the new Gardens by the Bay. There are 18 supertrees, some as high as 16 stories tall. Each is it’s own vertical garden, with over 162,900 plants covering them. 11 of the trees have solar panels to generate power. At night, the supertrees light up the evening with their own light show. The permanent exhibit opened June 29.
