This is one of the rarer hydrangeas - in a garden. That is, unless you count its offspring. This is the source of many, and many of the oldest, cultivated varieties of hydrangeas. The very similar ashy and silverleaf hydrangeas were formerly included in the species, so I guess in a sense they're offspring too. Common hydrangea grows in woods and along forested edges in AL, AR, CT, DE, FL(E), GA, IL, IN, KS, KY, LA, MA, MD, MO, MS, NC, NY(E), OH, OK, PA, SC, TN, VA, WV, NB, and NS. Beal Gardens, MSU, 7/1/17.
