Do You Have a Noxious Weed?
Upright, up to 4-feet tall with creeping-root system; reproduces by seed and root
Seedlings emerge in late April to May forming rosettes; flowers late spring to early summer
Very erect plant with shiny, spined leaves
Seeds are viable for up to 22 years
3/4" purple flower
Flower matures in late summer into dandelion-like white "puffball" which spreads the seed in the breeze
Repeated mowing, tilling, cutting or hand removal prior to seed production can provide suppression
Successful treatment will require several years
Apply Tordon, Milestone, or Curtail to growing plants through flowering
Repeated applications of 2,4-D, Banvel, or Roundup to actively growing plants
