Strangler fig
Strangler fig is the common name for a number of tropical and subtropical plant species, including some banyans and unrelated vines, including among many other species:
They all share a common "strangling" growth habit that is found in many tropical forest species, particularly of the genus Ficus.[1] This growth habit is an adaptation for growing in dark forests where the competition for light is intense. These plants begin life as hemiepiphytes, when their seeds, often bird-dispersed, germinate in crevices atop other trees. These seedlings grow their roots downward and envelop the host tree while also growing upward to reach into the sunlight zone above the canopy.[2][3]
An original support tree can sometimes die, so that the strangler fig becomes a "columnar tree" with a hollow central core.[4] It is also believed that the strangler fig can help the support tree survive storms.[5]
