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.

Not assessed for pets: one ASPCA listing was found, and the NC State non-toxic tag has no stated source, so it does not count as a second source.

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.
