The status of knapweeds (Centaurea spp.) as invasive species is very interesting and widely documented. However, it’s a topic that I’ve chosen to bypass in order to feature some of the many pollinators that swarm the knapweed bloom in the hot, muggy days of summer. I mow (brush hog) several sites once a year in order to arrest succession and maintain herbaceous habitat for wildlife. Grasses, goldenrods and knapweed dominate these managed openings. The knapweed bloom precedes the goldenrod bloom and appears to fill a void in the natural sources of nectar for pollinators.
