Longan trees are commonly grown in many subtropical and tropical countries with the majority of the production in Thailand, Cambodia, Taiwan, China, and Australia (Menzel et al., 2002). In the United States, major production occurs in Florida, Hawaii, and California.
Fresh longan fruit are now available in local markets in Thailand almost all year round. This is possible because off-season longan is now possible.
