 Plants: Forbs/Herbs
Magnoliopsida > Dipsacales > Dipsacaceae > Dipsacus fullonum L.
Synonym(s): Fuller's teasel, teasel
Common teasel is a biennial plant that exists as a basal rosette until flower stems develop. The erect flower stems reach 6 ft. (1.8 m) in height and support spiny flower heads that are covered with small, lavender to white flowers in April to September. Rosette leaves are lanceolate to oblanceolate and stem leaves are opposite, lanceolate and fused at the base. All leaves have short prickles on the midvein. Common teasel favors disturbed sites such as roadsides, ditches, waste places, riparian sites, fields and pastures in most of the continental United States. Only recently was common teasel distinguished from fullers teasel which was once cultivated for the dried flower heads used in wool processing. It is native to Europe.
