Spotted Knapweed

Thanks to Alert Flowerspotter Aaron who snapped this for me while at an autocross event with his brother in Ayers, Massachusetts. Growing through the concrete at an old airfield. Considered a noxious weed in many western states. One of its invasive species skills is: “low palatability” —meaning no one wants to eat it AND it’s “allelopathic”, meaning its roots send out a toxin that stunts the growth of nearby plants! Wily! Native to Europe.
