Star magnolia
Magnolia stellata
Family: Magnoliaceae
Pet & Human Safety
People: No hazard foundPets: Not on the ASPCA lists as we read them
ASPCA's Magnolia Bush page (Magnolia stellata) lists it as non-toxic to dogs, cats and horses. ASPCA is the only source we found, and one source is not enough to call a plant safe for pets, so it is not assessed as safe. Keep pets from eating it. Edibility is not researched: NC State's only edibility signal is bare tags with no descriptive detail, too thin to state as a safe-to-eat fact.
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.
