CommentsThe floral spikes from a cultivated form of Teasel were used to raise the nap of woolen fabrics. This was possible because the bracts of the receptacle in the cultivated form had hooked tips. In contrast, the wild form of Teasel (as described here) has bracts with straight tips. In horticulture, the dried floral spikes and their stalks are used in dried flower arrangements. In the past, the floral spikes and stalks were used as material in funereal wreaths, which were placed alongside the gravestones of the deceased. This is one of the reasons why Teasel occurs in cemetery prairies. With its spiny-looking floral spikes and prickly stems, Teasel has a distinctive appearance that resembles no native plant in Illinois. Another introduced species, Dipsacus laciniatum (Cut-Leaved Teasel), can be distinguished from ordinary Teasel by its pinnatifid leaves and straight bracts at the base of the floral spikes; these bracts spread outward, but they do not curl upward. The flowers of Cut-Leaved Teasel are white, while those of ordinary Teasel are usually pale purple or lavender; however, strains of Teasel with white flowers may occur in the wild. A scientific synonym of Teasel is Dipsacus sylvestris.
