Palmer’s amaranth

Palmer's amaranth (Amaranthus palmeri) is a species of amaranth, a genus of flowering plants in the family Amaranthaceae. Amaranths are known for their diverse uses, including as food crops for their nutritious leaves and seeds, and as ornamental garden plants. However, several amaranth species are considered noxious weeds.12

Palmer's amaranth is particularly problematic as it has developed resistance to the herbicide glyphosate, making it a troublesome pest in agricultural crops like cotton and soybeans in the United States. This weed is known for its competitiveness and ability to reseed itself readily.1
