A native tropical fruit tree growing wild in southern central and southern Florida. I have seen a few trees in wetlands as far north as Orlando. It's one of the most prolific trees in the everglades. Alligators sometimes eat the fruit hence the name Alligator apple. Its flood tolerance makes it the prefferred rootstock for most annonas. It is very invasive in Australia and shouldn't be planted there.

Seedlings: are resistant to salinity and the seeds can be grown with seawater. Seedlings raised outside can survive with seawater. Seedlings are found to be suitable as rootstocks for Custard apple and Sour sop.
Economic Importance:
Plants can be grown in swampy and marshy conditions. Can be used for aforestation purposes in coastal areas. Cuttings could be planted around the nursery bed to prevent the African giant snail from entering in the nursery beds.
