Threat:

Cut-leaved teasel is a perennial herb and flowers once then dies.  Common teasel (D. fullonum) is similar and invasive but with purple flowers, leaves not deeply cut. The common and cut-leaved teasels are European plants introduced to North America in the 1700's. Teasel is currently used in horticultural plantings and dried flower arrangements.  Teasel produces an abundance of seeds. A single teasel plant can produce over 2,000 seeds; up to 30-80% of the seeds may germinate. Seeds may remain viable for at least 2 years. Seeds may be water-dispersed, which allows dispersal over longer distances. Cut-leaved teasel threatens prairies and sedge meadows. 

 

Distribution:

Cut-leaved teasel has been reported in the United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) database in the Indiana county of La Porte.
