A very common, erect, and much-branched species with a finely haired stalk, growing from one to three feet high, in low grounds from Maine to Ontario, Wisconsin, Nebraska, South Carolina and Missouri, from June to September. The finely toothed leaf is long and narrow, and usually very short-stemmed. The numerous pink or white flowers have four small rounded and notched petals and eight yellow stamens. The flowers are fixed on the end of a slender pod and are generally nodding. The purple - stained pod splits open in the fall and frees a mass of cinnamon coloured fluff. The stem and leaves are often tinged with purple.
