yankeeweed, Eupatorium compositifolium

Three days ago we took a look at Appalachian joe-pye-weed, Eutrochium steelei. If you compare the flowers of yankeeweed to joe-pye, you will see they are very much alike. Not long ago, joe-pyes were Eupatoriums too. Then joe-pyes were separated to Eupatoriadelphus, and ultimately to the more efficient Eutrochium. The difference is opposite leaves with Eupatorium, and whorled leaves with joe-pyes. Yankeeweed grows mostly in sandy areas in AL, AR, FL, GA, KY, LA, MS, NC, OK, SC, TN, TX, and VA.
