Toxic to pets

No ASPCA page was found for this plant, and the NC State page has no poison section. Not listed means no pet-safety verdict was found, not that the plant is safe. Keep pets from eating it and call a vet or the ASPCA Poison Control line if a pet seems unwell.

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