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 epiphytes, when their seeds, often bird-dispersed, germinate in crevices atop other trees. These seedlings grow their roots downward and envelope 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, leaving a "columnar tree", central core empty, of the Strangler Fig.
