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.

The safety check found no ASPCA page for this plant, and NC State's 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.
