Flowering stems may reach 6-7 feet in height. The two species may hybridize. The common and cut-leaved teasels are European plants introduced to North America in the 1700's. Teasel is currently used in horticultural plantings and dried flower arrangements. Teasel grows in open, sunny habitats that range from wet to dry levels.
Optimal conditions seem to be mesic habitats.
Roadsides and heavily disturbed areas are the most common habitats of teasel. Teasel sometimes occurs in high quality prairies, savannas, seeps, and sedge meadows. Both species have become severe threats to northern Illinois natural areas. Rapid expansion of the range of cut-leaved teasel has been observed in several midwestern states, including southern and western Wisconsin. Movement has been documented along highway systems, where dispersal is aided by mowing equipment.
