Audrey Hepburn tours more than 50 botanical wonders around the globe, including Monet's garden in Giverny, France, and George Washington's Mount Vernon, Va., home. The Emmy-winning series aired on PBS in 1993, shortly after Hepburn's death. In 1996, HGTV aired two `new' episodes of the series, each of which contained previously unseen footage of her in the tropics and the Far East.
