Can you eat it?

For peopleNot well documented

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

For petsNot well documented

It isn't on the ASPCA plant list, and NC State Extension doesn't flag it for pets. For context only: ASPCA lists a related species, Hypericum perforatum (“Klamath Weed”), as toxic to dogs and cats. That doesn't tell us about this species, so keep pets away to be safe. ASPCA
