1Bring water and sugar to a boil in a medium saucepan over medium heat. Stir in the rhubarb, turn heat to low, cover, and simmer until rhubarb is soft, 10 to 15 minutes. Mash and chill in the refrigerator, about one hour.
2To serve, mix the grapes, orange, strawberries, apple, peach, plum, cherries, and blueberries with 2/3 cup of the rhubarb sauce. Stir gently, but thoroughly to coat. Refrigerate for at least two hours to allow the flavors to blend.
