Nannyberry is also called sweet viburnum even though the aroma is kind of yucky. Also, sheep viburnum. Where the nannies and sheep come into the story is a mystery to me. But these quarter inch flowers, all in a bunch, with bunches and bunches all over a 30 foot tree, are a late spring delight. Nannyberry grows in damp ground in thickets and borders in AL, CO, CT, GA, IA, IL, IN, KY, MA, MD, ME, MI, MO, MN, MT, ND, NE, NH, NJ, NY, OH, PA, RI, SD, VA, VT, WI, WV, WY, MB, NB, ON, QC, and SK(T).
