How complete this information is
We have not researched the safety of this plant yet.
Toxic to pets
No ASPCA entry found.

Not assessed for pets. A single source, or an ASPCA page plus a bare NC State tag, is not enough to show a plant is safe, so the app makes no pet-safety claim either way.

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.

Emergency number source: U.S. federal law (47 U.S.C. § 251(e)(3)), read 2026-10-07.
