Cutleaf teasel is a threat to Minnesota’s pastures and natural areas. Native to Europe, teasel was introduced as early as the 1700s, for both industrial and ornamental purposes. The fabric industry placed teasel on spindles, spinning fabrics across them to raise the nap of fibers. Gardeners planted cutleaf teasel for its stately form. Flowers and seedheads are used in dried floral arrangements. Cutleaf teasel escaped cultivation and now displaces desirable vegetation. The related common teasel was similarly used and was also a source of wool dye.
Cutleaf teasel grows in open, sunny habitats such as roadsides and pastures. It prefers disturbed areas, but can invade high quality areas such as prairies, savannas, seeps, and sedge meadows.
Teasels are prolific seed producers with most seed falling near the parent plant. The result is expansion of existing infestations. Long range dispersal starting new infestations can occur by a variety of means. Seed can float along riparian corridors, drift with the snow, journey along transportation corridors and recreational trails from seed shed from soil on tires and vehicle undercarriages. It can also be spread on mowing equipment. Teasel has been noted in or near graveyards, spread by seed from dried floral arrangements. Birds can consume, then distribute teasel seeds. It can be found in all northern states from Massachusetts to Colorado and in Oregon. In Minnesota, cutleaf teasel is reported in multiple counties including Clearwater, Houston, Hubbard, Mower, Olmsted, Pope, Ramsey, St. Louis, Wabasha, and Winona.

The teasels form large dense stands that choke out desirable plant species. This can reduce forage, wildlife habitat, and species diversity.
