Both native and introduced species of Philadelphus occur in North America. Sweet mock-orange is an immigrant from southern Europe, popular as an ornamental shrub because of its beauty and delightful aroma. Strangely, some cultivated varieties have little scent. This species was first collected from the wild in Michigan and here in Lenawee County in 1983, and misidentified as P. inodorus. Perhaps that was in part because it had little aroma? Sweet mock-orange has now been reported from CT, GA, IL, IN, KY, MA, MD, ME, MI, MN, MO, NC, NH, NJ, NY, OH, PA, RI, SC, VA, VT, WI, NB, ON, and QC. Lenawee Co MI, 6/14/14. Hydrangea family, Hydrangeaceae.
