Hairy angelica is a special concern plant in Michigan. That means if trends continue, it will become threatened. Here in this county I've seen it twice. It is now gone from both sites. But not because of human activity. Things naturally change. Both sites have become more shaded by trees, and hairy angelica is a plant of open ground. Sometimes human activity helps. The population of the image had moved into clearings at an abandoned development. The butterflies liked it too. There were crowds of them on that day. This angelica grows in AL, AR, CT(S), DE, FL, GA, IL, IN, KY, LA, MA, MD, MI(S), MN, MO, MS, NC, NJ, NY, OH, OK, PA, SC, TN, VA, WV, and ON. Wayne Co MI, 8/1/14.
