Amaranthus palmeri

Amaranthus palmeri is a species of flowering plant in the amaranth genus. It has several common names, including Palmer's amaranth, Palmer amaranth, Palmer's pigweed, and carelessweed. It is native to most of the southern half of North America. Populations in the eastern United States are probably naturalized. It has also been introduced to Europe, Australia, and other areas.

Palmer amaranth is a fast-growing weed that has been noted as a threat to production of genetically modified cotton and soybean crops in the southern United States because in many places, the plant has developed resistance to the widely-used herbicide Roundup.[1] [2]
