Pet & Human Safety
People: Not researchedPets: Not on the ASPCA lists as we read them
Non-toxic to dogs, cats, and horses per ASPCA's Rose entry. The thorns are a mechanical/puncture hazard, not a toxicity risk: worth mentioning to a pet owner even though it isn't a poisoning concern.
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.
