Can you eat it?
None of the sources we checked (NC State Extension (no edibility or poison notes on its page), USDA PLANTS) say whether it's edible or poisonous for people. NC State Extension
ASPCA's entry “Rose” (Rosa Species), which covers the whole genus, lists it as non-toxic to dogs, cats and horses. Eating lots of any plant can still upset a pet's stomach. ASPCA
🌿 Never eat a wild plant unless you're certain of its ID; this isn't medical advice. Worried about a person? Call Poison Control at 1-800-222-1222. Worried about a pet? Call your vet.
