In the photograph above, a strangler fig embraces a cypress tree in Big Cypress National Preserve in Florida. The strangler fig is (Ficus aurea) one of the most striking plants in the Big Cypress swamp in Florida. It grows around the host tree, actually strangling its host over time.
The strangler fig is an epiphyte, a plant that grows on another plant but is not parasitic, such as the numerous ferns, bromeliads, air plants, and orchids growing on tree trunks in tropical rainforests. However, the strangler fig is the only epiphyte that will affect the host in which it grows. The strangler fig grows very slowly as it matures, extracting water and nutrients directly from the atmosphere. As the plant gets larger, it may grow both up and down the trunk of the host tree. Eventually, the strangler fig will reach the ground and start growing more rapidly. The strangler fig encircles the roots of the host tree, eventually killing it. As the host tree rots away, a hollow void is left with the strangler fig standing alone.
