Mountain yam + American pokeweed

Dioscorea pentaphylla is a species of flowering plant in the yam family known by the common name fiveleaf yam. It is native to tropical Asia or eastern Polynesia, and it is present elsewhere as an introduced species. This species is a prickly vine that twines counterclockwise around objects and other plants. It may reach 10 meters in length. The alternately arranged leaves are compound, divided into 3 to 5 leaflets each up to 10 centimeters long. The plant produces horseshoe-shaped bulbils about a centimeter long. New plants can sprout from the bulbils. Flowers are borne in spikes. The vine grows from a tuber. Specimens may be 3 pounds in weight and may be located over a meter underground. The tubers of the vine can be cooked and eaten.

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.
