Newton's Mayor Warren will host a special daffodil planting ceremony in front of the Johnny Kelly statue on Heartbreak Hill. “Marathon Daffodils,” a group comprised of residents from the greater Boston area, was created last year to plant daffodils along the entire marathon route in tribute to the victims of last year’s bombing. As one of the marathon’s host communities, Newton welcomes the plantings along the route, and Mayor Warren invites all residents to join him for this special ceremony, which will include clergy and local officials.  The Johnny Kelly statue is located at the intersection of Commonwealth Avenue and Walnut Street, across from Newton City Hall.
