Strangler fig is the common name for a number of tropical and subtropical plant species in the genus Ficus, including those that are commonly known as banyans. Some of the more well-known species are:

These 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. Strangler figs suck up the nutrients from its victims,[citation needed] causing them to die eventually. These plants are hemiepiphytes, spending the first part of their life without rooting into the ground. 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] However, it is also believed that the strangler fig can help its support tree survive storms.[5]

Strangler trees are able to colonize the challenging habitat found on the sides of buildings in urban areas. Strangler figs in the tropics are pre-adapted to adopt an aerophytic as well as "acrobatic" urban life by clinging on to building envelopes.[6]
