Discussion
Hylocereus undatus is sporadically naturalized in tropical and subtropical regions worldwide where it is cultivated for its large, edible fruits and beautiful flowers, which are among the largest in the cactus family. In Florida, H. undatus has escaped from cultivation in nine counties, forming large colonies in some areas. Individuals of this species grow prolifically and may soon overrun their substrate. Whether populations of H. undatus in the United States are merely persisting or are also reproducing sexually remains unclear.
The vernacular name night-blooming cereus has been applied to several genera of cacti with large, nocturnal flowers.
