Can you eat it?

For peopleNot well documented

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.

For petsNot well documented

It isn't on the ASPCA plant list. For context only: ASPCA lists a related species, Lathyrus latifolius (“Sweet Pea”), as non-toxic to dogs and cats. That doesn't tell us about this species, so keep pets away to be safe. ASPCA
