I felt like Alice in Wonderland, walking amongst the super trees in Singapore’s Garden by the Bay. The grove of 16 story-tall “trees” completely dwarf everything else around them.  These man-made structures are built on reclaimed land as part of an efficient green space project.  Each tree is surrounded by a steel skeleton that is used as the framework for planting various flowers, ferns and  other vertical climbers.  At the top are built in solar panels used as the main energy source to keep the structures lit at night.   These trees are as fantastical as they are practical and they are an iconic part of the city.
