Safety Overview
1.Teasel — At a Glance
Teasel, known scientifically as Dipsacus fullonum, is a distinctive herbaceous biennial plant. It belongs to the Caprifoliaceae family and was formerly classified under Dipsacaceae. It typically grows to an impressive height of 1 to 2.5 meters. This robust plant has prickly stems and leaves. The leaves often form cup-like structures at their bases that can hold rainwater.
The plant's most recognizable feature is its ovoid to cylindrical flower head. The head holds numerous small, purplish-pink flowers encircled by stiff, spiny bracts, which give it a cone-like appearance. Its leaves are wrinkled, lanceolate, and generally arranged in opposite pairs. They have a characteristic downward-pointing prickly texture on the underside of the midrib. Teasel is native to temperate regions of Eurasia and North Africa.
Dipsacus fullonum has naturalized across various parts of the world. It thrives in disturbed habitats such as roadsides, meadows, waste grounds, and riverbanks. It prefers well-drained soils and ample sunlight, which shows its adaptability and widespread distribution.
