Dipsacus fullonum, commonly known as common teasel, is a biennial plant native to Europe and parts of Asia. It typically grows up to 2 meters tall and features tall, spiky flower heads that bloom in summer. The plant has serrated leaves that form a rosette in its first year and produces small, tubular flowers that attract various pollinators. This species is often found in disturbed areas, such as roadsides and fields, and is known for its distinctive appearance. Dipsacus fullonum has been historically used in the textile industry for carding wool, thanks to its prickly flower heads, which help separate fibers.
