Maclura pomifera is native to southwestern Arkansas, southeastern Oklahoma, and Texas; it is introduced and naturalized elsewhere in the United States. Collections in California, Connecticut, Massachusetts, Rhode Island, and Washington appear to represent isolated escapes.

Maclura pomifera has been widely used in fencerows on farms and along roadways in the midwest and eastern states as windbreaks and wildlife shelter.

The Comanches used Maclura pomifera as an eye medication (D. E. Moerman 1986).
