Can you eat it?

For peopleEdible (per NC State Extension)

NC State Extension notes: “Leaves, stems and bulbs have garlic onion flavor high in vitamin C. If harvesting in the wild, leave the bulbs and one leaf in the ground to promote sustainablity.” 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, Allium ampeloprasum (“Leek”), as toxic to dogs and cats. That doesn't tell us about this species, so keep pets away to be safe. ASPCA
