Sweet Pepperbush Clethra alnifolia aka Poor Man's Soap. The leaves produce a lather when mixed with water and rubbed vigorously. Most sources say it is the flowers, but I have never had success with the flowers lathering. The flowers smell spicy and sweet. Pollinators love it. It is an air purifier meaning it can take polluted air and give back pure oxygen. I am drying the leaves to see if I can extract a "soap" that will lather. It never hurts to try, and I might learn something new.
