Answer: Common teasel (Dipsacus fullonum) is considered an invasive weed in most parts of the U.S. but is not on the noxious weed list in Mass. so you can grow it in your garden without concern of breaking the law. In fact, many gardeners cultivate teasel because they use the dried seed heads in dried flower arrangements. You can sow the seeds in your garden now and they will germinate in the early spring and grow to maturity by the end of next summer.
Best wishes with your garden!
