The Wonderboom is a dense grove of parent and daughter trees of the species Ficus salicifolia, that descended from a central bole of about a thousand years old. It is situated in the Wonderboom Nature Reserve, Pretoria, and two circular walkways currently protect it from pedestrian traffic around its trunk and roots. As it has grown, its outlying branches have rooted themselves around the parent tree. This has repeated until there are now three layers of daughter trees encircling the mother fig, with 13 distinct trunks, covering an area with a diameter of over 50 metres (160 ft).
