The ylang ylang flowering tree originates in the Pacific region, where you can find it thriving on several different and widespread islands. That natural range includes places such as Polynesia, Micronesia, and Madagascar. In those locations, the ylang ylang flowering tree lives in rainforests where the weather is consistently warm and humid. Since gaining ornamental recognition, this tree has spread to many countries, but it grows best where conditions are similar to that which you would find in its home range.
