The origin of the wax apple (Syzygium samarangense) is the Malay Archipelago and the Greater Sunda Islands. It has been grown in Southeast Asia for thousands of years. The fruit got its name because the skin has a shiny, waxy look. It is also called the Java apple or water apple because of its high water content.

The fruit was brought to the Caribbean and Central America in the 18th century. Today, Thailand, Indonesia, and Taiwan are the world's biggest growers of the fruit. They grow special types like the "Black Pearl" wax apple for export.
