The small bluish-lavender flowers of teasel (July-October) are tubular and are borne in a flowerhead surrounded by sharp spiny bracts. A native of Europe, teasel is naturalized in North America from Quebec to Ontario, from New England south to North Carolina and west to Utah, and in the Pacific Northwest states, especially in areas where teasel was once cultivated.
