Ficus elastica prefers bright sunlight but not hot temperatures. It has a high tolerance for drought, but prefers humidity and thrives in wet, tropical conditions. Ornamental hybrids (such as Robusta) have been derived from "Ficus elastica" with broader, stiffer and more upright leaves than the wild form. Many such hybrids exist, often with variegated leaves.
