Seeds from open flowers are held in a flat pod, pointed at both ends, that dries when mature and twists to release the seeds. Seeds from closed flowers are held in round pods with a single seed each. The roots and the cooked seeds from under the ground are edible.{{PFAF}}{{cite book |last1=Niering |first1=William A. |author-link1=William Niering| last2=Olmstead |first2=Nancy C. |title=The Audubon Society Field Guide to North American Wildflowers, Eastern Region |year=1985 |orig-year=1979|publisher=Knopf |isbn=0-394-50432-1 |page=520}} The seeds which become subterranean from flowers on stolons give it the name hog peanut.{{Illinois Wildflowers|savanna/plants/hog_peanut|Hog Peanut (Amphicarpaea bracteata)}} {{Cite web |url=http://illinoiswildflowers.info/savanna/plants/hog_peanut.html |title=Hog Peanut (Amphicarpaea bracteata) |access-date=2022-11-16 |archive-date=2019-08-26 |archive-url=https://web.archive.org/web/20190826102326/http://illinoiswildflowers.info/savanna/plants/hog_peanut.html |url-status=bot: unknown }}
