The Columbia SWCD needs your help to identify Meadow knapweed sites throughout Columbia County!
This is a relatively new invasive species in our area and is rapidly spreading along roadsides, trailheads, parks, and other highly managed areas. We have found several sites along Crown Zellerbach Trail. So if you enjoy hiking the trail please be on the look out for this plant.
Meadow knapweed is best identified in summer when it bears pretty purple flowers on top of a dark brown involucre. Leaves are narrow and alternate along rigid stems.
