A tall, striking native biennial, known for its large prickly seed heads which persist well into winter on roadside verges, waste ground and field edges. The lilac-pink conical flower heads are borne above serrated leaves in mid to late summer, attracting lots of bees, butterflies and other beneficial insects. The seed heads are also a good source of food for birds. Teasels are an excellent architectural plant for the back of garden borders or in wildlife gardens where they will self-seed freely for a continual display. Dried teasel flowers also make an attractive and textural addition to cut flower arrangements. Height: 1.5m (5′). Spread: 45cm (18″).
Common teaselis a biennial or sometimes monocarpic perennial forb. The fruits are a four-angled achene, each containing a single seed. Common teasel can produce more than 2,000 seeds per plant. The flowers are purple or white with spiny, awned bracts at the base. The flower head is generally egg-shaped, with a square base. The floral bracts at the base of the head are generally longer than the head. Rosette leaves are conspicuously veined, with stiff prickles on the lower midrib and appear to be wrinkled. Stem leaves are simple, opposite, net-veined, stalkless, and clasp the stem. Mature plants can grow up to or over six feet tall. The taprooted stem is rigid with several rows of downward turned prickles. Plants die after production of seed has occurred.
It escapes cultivation and grows in garden areas, along creeks, pond edges, roadsides, abandoned fields and other disturbed sites. It is also grows into agricultural areas, fallow fields, pasture lands and hay meadows. It prefers open, sunny habitats and can survive in a range of wet to dry conditions.

A number of options are listed in the PNW Weed Management Handbook. Please refer to the PNW Weed Management Handbook, or contact your county noxious weed coordinator.
Maintenance of healthy of plant communities will help prevent re-infestation by common teasel. After the control of infestations, seed and plant areas with competitive grasses, forbs and other desirable plant species.
Where does it grow?
The second year flower stems grow 0.5-2 meters tall, are striate-angled and increasingly prickly going upward. Stems are pithy or hollow and have opposite branching.
Rosettes can be dug up, though it is important to remove as much of the root as possible to prevent resprouting. Flowering stalks can be cut from plants where flowering has already initiated and not before or stems will resprout. Cut flower stalks should be removed from the area.
It reproduces from seed. A single flowerhead can on average produce around 850 seeds and plants typically produce 1-40 flowerheads. Seeds can be dispersed by floating on water, in mud, soil movement, human activities and by animals and birds.
There are currently no biological control agents available for common teasel.
