Rubber plant
Ficus elastica
Ficus elastica, the rubber fig, rubber bush, rubber tree, rubber plant, or Indian rubber bush, Indian rubber tree, or rambung is a species of flowering plant in the family Moraceae, native to eastern parts of South and Southeast Asia. Its common names reflect its historical use as a source of rubber within its native range, but it is not used in the modern commercial-scale production of natural rubber.
