How complete this information is

We have not researched the safety of this plant yet.

Toxic to pets

No ASPCA entry found.

Genuinely unassessed by ASPCA, not cleared. UF/IFAS EP009 separately notes the fruits as 'irritating,' which is a physical/mechanical caution rather than a sourced systemic-toxicity claim, and is disclosed here rather than folded into the pet-toxicity verdict. For context, as with Queen Palm and Cat Palm: most true palms ASPCA has evaluated are rated non-toxic, but that pattern isn't extended into an inferred verdict for an unassessed species: recorded as unconfirmed rather than guessing.

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

Poison control

If someone has collapsed, cannot be woken, is having a seizure or has trouble breathing, call 911 now. For any other possible poisoning, call Poison Help: 1-800-222-1222.
