Back in the sandhills I rememberd seeing alllot of wild asparigas in fence rows and out in hay meddows.
while fixing fence you could find Morrels if the weater was right for them.
Wild Plumbs, Hack berries, choke cherries, wild onion, cattails, ground cherries, goose berries, rasberries growing wild in the creek bottoms and around old farm steads, same for fruit orchards and nut trees, had a big old Black Walnut in one pasture, there was always something to eat.
