is primarily an eastern US species, introduced across the west. The rigid, grooved, green stems grow up to 3 feet tall have a covering of long, rough hairs; they are topped by one or several large flowerhead(s), each up to 3 inches across. Flowers have between 8 and 20 yellow ray florets, angled downwards (drooping), and often curving more at the tips. Rays have a few pronounced lengthwise grooves. At the center of the flower is a hemispherical group of reddish-brown disc florets, up to an inch in diameter. The upwards-pointing, lance-shaped basal leaves are also quite large, and have long stalks; stem leaves are stalkless and narrower.
