How complete this information is
The safety information on this page is partial. Where a source covers a point, it is shown; where none does, the page says so.

Toxic to pets
No ASPCA entry found.

No ASPCA page for this species. UF/IFAS warns of a disease in animals that eat certain parts of the tree ("jumbey"). Do not treat as pet-safe.

PlotAndPetal cannot tell you whether a plant you found can be eaten. Only someone who can see the plant can identify it.
