Agave decipiens might have been introduced from Latin America by Native Americans; it is not otherwise known from the wild. The proliferation of chromosome numbers suggests prolonged human propagation and a probable hybrid origin. Until demonstrated otherwise, the species is considered a rare and localized native species known only from a few sites in southern Florida. H. S. Gentry (1982) discounted the suggestion that A. decipiens was found on the Yucatán peninsula of Mexico. He considered such plants to be A. angustifolia.
