Amaranthus retroflexus is a species of flowering plant in the family Amaranthaceae with several common names, including red-root amaranth, redroot pigweed, red-rooted pigweed, common amaranth, pigweed amaranth, and common tumbleweed.[4]

Outside of its native range, it is considered a weed. Although it may be toxic if eaten uncooked, or in excess by livestock, it can be consumed as a vegetable or as fodder.
