Teasel, a tall biennial weed, is being introduced into various parts of Iowa by means of bouquets and ornamental cemetery wreaths sold especially at Christmas time, but also throughout the year. Mature teasel heads are used in the and bouquets. Seeds from these heads scatter during transportation and use in the cemetery. If the wreaths are not destroyed by burning, they can serve as the initial infestation. If uncontrolled, this weed can rapidly infest surrounding areas. The teasel heads in the bouquets and wreaths are usually spray-painted with various colors to make them attractive.
