Keys to ID:



Mech: Hand pull from April to June, after they begin to bolt, until they are through flowering, and while the seed pods are still green. Plants in flower or even in bud are able to form viable seeds even after they are pulled, therefore plant pieces must be carefully bagged and disposed of. In areas where mature plants are pulled, there are usually many small rosettes and seeds left in the soil. Carefully search the area for rosettes and dig them up with care as roots break off easily and re-sprout (King County Noxious Weed Control Program 2010).
