American pokeweed + Prairie turnip

American Pokeweed (Phytolacca americana) is a large semi-succulent herbaceous perennial plant growing up to 10 feet (3 meters) in height. It is native to eastern North America, the Midwest, and the Gulf Coast, with more scattered populations in the far West. It is also known as Virginia poke, American nightshade, cancer jalap, coakum, garget, inkberry, pigeon berry, pocan, pokeroot, pokeweed, pokeberry, redweed, scoke, red ink plant and chui xu shang lu. Parts of this plant are highly toxic to livestock and humans, and it is considered a major pest by farmers. Nonetheless, some parts can be used as food, medicine or poison. The plant has a large white taproot, green or red stems, and large, simple leaves. White flowers are followed by purple to almost black berries, which are a good food source for songbirds such as Gray Catbird, Northern Cardinal, Brown Thrasher, and Northern Mockingbird.

Psoralea esculenta (prairie turnip) is an herbaceous perennial plant native to prairies and dry woodlands of central North America, which bears a starchy tuberous root edible as a root vegetable. The plant is also known as Pediomelum esculenta. English names for the plant include tipsin, teepsenee, breadroot, breadroot scurf pea, and pomme blanche. The prairie turnip was a staple food of the Plains Indians. A closely related species, Psoralea hypogaea, the little breadroot, is also edible, although the plant and root are smaller. Another species, Psoralea argophylla, was probably harvested for food only in times of famine.
