Can you eat it?
None of the sources we checked (NC State Extension (no page for this plant), USDA PLANTS) say whether it's edible or poisonous for people.
It isn't on the ASPCA plant list. For context only: ASPCA lists a related species, Kalmia augustifolia (“Lambkill”), as toxic to dogs and cats. That doesn't tell us about this species, so keep pets away to be safe. 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.
