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.
ASPCA's entry “Good Luck Plant” (Oxalis spp), which covers the whole genus, lists it as toxic to dogs, cats and horses. Signs include: All parts of the plant have toxic potential, although the possibility of serious effects is usually limited to ingestions of large quantities. Consuming Oxalis species can produce colic in horses… ASPCA
