Time of bloom: July to September.
Seed-time: August to October.
A near relative of the preceding plant and even more pernicious because blooming earlier. It is taller, stouter, with fewer but larger blossoms, the heads solitary at the ends of the many branches and more than an inch broad. Stem two to three feet tall, stiff, woody, rough, and gray with close-pressed hairs which are persistent. Leaves narrowly oblong, obtuse at apex, the upper ones rounded at base and sessile, the lower ones narrowing to a petiole; they are hoary with stiff, appressed hairs, the larger, lower ones with bristly, fringed bases. Bracts of the involucre awl-shaped and very hairy. Achenes three- to five-ribbed, the outer row of the double pappus very spreading and bristly.
Means of control should be the same as for the preceding plant.
