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, 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
