Arnoglossum atriplicifolium (pale Indian plantain) is a perennial North American wildflower in the sunflower family. It is widely distributed through the central and eastern states of the United States from the Atlantic Coast westward as far as Kansas, but it is listed as endangered in the state of New Jersey. Arnoglossum atriplicifolium is a large perennial up to 300 cm (120 inches or 10 feet) tall, spreading by means of underground rhizomes. Stems are usually unbranched. Flower heads are white, sometimes with a bit of green or purple, with disc florets but no ray florets.
