Root was Tony-nominated for Best Featured Actress in a Play for her performances in The Norman Conquests trilogy of Living Together, Round and Round the Garden and Table Manners that transferred from London's Old Vic to Broadway's Circle in the Square in 2009.
In the play, "it's Andy Griffith's 21st Birthday. Not that he's counting. But his mother Carol (played by Root) is. Counting the minutes until he arrives, counting the unexpected guests, counting the times that this has happened before." Accoring to press materials, The Herd is a "witty and heartfelt look at family life when it doesn’t turn out quite the way you imagined."
