The rusty-leaf fig is a strangling fig, which begins life in the wild as a seedling that grows on other plants (hemiepiphyte) or rocks (lithophyte), eventually reaching a massive size with a large buttressed trunk. In cultivation they are planted as free standing trees that form a large dark canopy and no aerial roots in drier areas. A great deal of leaf size variation exists in this species as well as variegated cultivars. Ficus rubiginosa has a HPWRA (Hawai'i Pacific Weed Risk Assessment) score of 7 (High Risk).
Native to Eastern Australia.
