Some Ficus species have adapted to grow thick aerial roots. These roots elongate and thicken, sometimes becoming modified trunks to later support the full grown fig. Particular figs adapted by growing too much of these roots and eventually crumbling the old support they previously depended on. In cases where the old support is a tree, the ficus would tend to strangle the host and eventually kill it off, hence the common name strangler fig.
The most common name given to strangler figs in the Philippines is balete. Balete is a coined word for a number of species like Ficus concinna (dalakit), Ficus philippinensis, Ficus benjamina (salisi) and much more. Baletes are common even urban areas. Nowadays they could be found being used in landscape because of their ease in maintenance. But wild crafted specimens also abound in the most unlikely places like roof eaves of old structures. These are commonly the puzzler plants, making spectators wonder how the tree was planted on such a high place not easily reached by people. The answer is nature.
