This tree, estimated to be more than 35 years old, is probably of the same age as Tai Hing Estate. Ficus elastica is an evergreen tree of the Moraceae family and characterised by fast growth rate and luxuriant foliage. Aerial roots of F. elastica that grow downward from horizontal branches can, upon reaching the ground, become woody and eventually develop into prop roots, providing increased support and anchorage to the tree. As with many species of Ficus, India-rubber Tree can form a wide canopy that gives excellent shade from the sun.
