Walking along the footpath in Hupao Park, tourists will come across a lake with tiny golden flowers tucked away among a luxuriant Chinese fir grove. The golden flower, spatterdock by name, is nicknamed "three-inch golden lotus" as it resembles water lily in shape but is much smaller in size. 

Amazingly, the height of the tiny flowers changes with the height of the water surface. As spatterdock relies on tiny insects to pollinate, it usually adapts its height to suit the changing height of the open water area so as to stand above water to facilitate pollination.  

Recently, tourists have been amazed by a couple of naughty mandarin ducks that frequent the pond every day to enjoy themselves among the "three-inch golden lotus".
