I knew this moment would come. And here we are with absolutely nothing clever to say about Hairy. There are a lot of penstemons, all beautiful to look at. Fortunately not all involving unexpectedly treacherous roadside stops like mat penstemon did. Sooner or later the survival rate would go down. This one grows in open woods and fields in CT, DE, IL, IN, KY, MA, MD, ME, MI, MN, NH, NJ, NY, OH, PA, RI, TN, VA, VT, WI, WV, ON, and QC. Ives Fen Preserve, Lenawee Co MI, 5/29/11.
