PlantFiles: Pond Apple, Alligator Apple
Annona glabra

The pond apple is a medium sized tree that grows in deep wetlands throughout south Florida. The green-yellow fruit is food to many animals including racoons and squirrels. The bark is an excellent home for orchids and other air plants. This is a tropical with some cold tolerance but will suffer in a frost.

The plant is found in Andaman and Nicobar Islands, India. Dr D.R.Singh, Dr S.Senani and Dr. R.P.Medhi at Central Agricultural Research Institute, Port Blair, have done extensive work on propagation, fruit, seed characteristics and nutritional profile.

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.

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.

This plant is a decleared pest in australia threatening many ecosystems

well i was always told it was apple custard...knew it wasn't and just found out today what it is..i have lots of seeds and plants if anybody wants any..i am in palm bay fl..near u.s.1..on the coast...
