This elegant plant can climb like a vine, but often looks like ground cover.

Its most well-known common name (“hog peanut") is dismissive if not defamatory in origins; it was a food that Europeans disdained, though the underground seeds were eaten by indigenous Americans, and the plant was even sacred to the Osage. “Ground beans" might be the best intuitive name. This plant produces some flowers above ground for pollination, but other flowers (self-pollinating) develop below the ground. New concept for the week: "underground flowers"!
