Thespesia populnea is sometimes grown as a shade tree, and has been found in coastal Florida from Brevard and Sarasota counties south to Monroe County, most commonly on the Florida Keys. The species is thought to be native to coastal areas of the Indian and Pacific oceans and widely introduced and naturalized in the New World. The capsules float and have distributed the seeds widely. It has been used widely for food, lumber, fiber, and medicine.
