brittlestem hempnettle, Lamiaceae, Galeopsis tetrahit

Aha! A pearly everlasting! I need a good shot of that.
So I pulled over and walked back. But what's that there in the ditch? Hempnettle was collected here in Lenawee in 1966. I've been keeping a eye out for it for a long time. In the end I had to go way north, almost to Paradise, to see it. And to discover that the Paradise I read about in Steve Hamilton's novels is a real place. Hempnettle is a Eurasian that has a reputation of following people around, wherever we're growing crops. Wonder why? It is one of the few plants in the mint family with an unpleasant aroma. So far it has turned up in AK, CA, CO, CT, IA, ID, IL, KY, LA, MA, MD, ME, MI, MN, MO, MT, NC, ND, NE, NH, NJ, NY, OH, OR, PA, RI, SD, TN, VA, VT, WA, WI, WV, acroass Canada except fot NT and NU, and on SPM.
