Common teasel is a native of Europe and was introduced to the United States in the 1700s. Like its close relative cutleaf teasel, it was used in the textile industry to raise the nap on woolen cloth and as an ornamental in gardens and floral arrangements. It escaped cultivation and has since spread throughout the United States.
Common teasel prefers sunny areas and is tolerant of wet to dry soils. In Western states, it is found growing along roadsides, in pastures, and sedge meadows. It was recently discovered growing along a trout stream in southeastern Minnesota.
Common teasel is a prolific seed producer. Many of the seeds germinate where they fall next to the parent plant, and this allows the plant to form a monoculture that becomes difficult to manage. Seeds can be carried by water and teasels threaten riparian areas. Humans can also aid spread by using the fresh or dried flowers in decorative arrangements.

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