Dipsacus fullonum, commonly known as the common teasel, is a biennial plant native to Europe and parts of Asia. It typically grows to a height of 1 to 2 meters and features tall, spiky flower heads that bloom in summer. The plant has serrated leaves that grow in a rosette during its first year and then develop a tall flowering stem in the second year. The flowers of Dipsacus fullonum are purple and attract various pollinators, including bees and butterflies. This species is often found in disturbed areas, such as roadsides and meadows, and is known for its use in traditional textile processing, where its dried flower heads were used to raise the nap on fabrics.
