Manilkara zapota is thought to be native to the Atlantic and Pacific coasts of Belize, Guatemala, Mexico, and Nicaragua, and is widely cultivated elsewhere. In southern Florida, it is commonly cultivated and occasionally naturalized. The latex was the primary source of chicle, a major constituent of chewing gum before the substitution of synthetics. Mayans used the wood for lumber, but now the species is protected there in favor of preserving the fruits, which are highly prized.
