A tall wild plant with a stiff, egg-shaped flower head covered in many small sharp points, so it feels prickly and hooky when you touch it. It grows by roadsides and in fields in Europe and North America, and after it dries it turns brown and stands through the winter — you often see the dry heads in flower arrangements, and birds pick seeds out of them. The reason this plant has an English name at all is the old cloth trade. Before machines, workers dragged the dried, hooked heads across woollen cloth to pull the fibres up and make the surface soft and fluffy. That job is also called teaseling, and the same word can be used as a verb for doing it. This is why the plant is sometimes called fuller's teasel — a fuller was a worker who prepared cloth. It is a narrow, specialist word today: gardeners, birdwatchers, and people interested in old crafts use it; most English speakers would just point and say "that spiky plant". It is also spelled teazel or teazle.
