There are roughly 15 dogwoods native to the US and Canada. It depends how you divide the species. At least two, including this one, are not clear. Many would call this C. racemosa, and separate it from some of its more southern kin. Most of the dogwoods don't have large showy bracts around the inflorescence like flowering dogwood. Either way, they are pretty. This bunch of flowers is about an inch across. In most species it's larger, up to about three inches. Cornus foemina, variety racemosa, grows in AR, CT, DE, IL, IN, KY, MA, MD, ME, MI, MN, MO, NC, ND, NE, NH, NJ, NY, OH, PA, RI, SC, SD, TX, VA, VT, WI, WV, MB, ON, and QC. Lenawee Co MI, 6/10/16.
