ROADWEEDS OF THE UPPER PENINSULA
|Spotted Knapweed (Centaurea maculosa)|
There's about 11 species of knapweed in Michigan, all are exotics from Europe or the Mediterranean region. The leaves tend to be a sage-green color. C. maculosa may be the most aggressive of the species, but other species cause problems, too. Another good plant to eradicate where ever you find them. In addition to looking like wild bergamot (a native species), knapweeds might also be confused with thistles.
