Drain all fruit (oranges, fruit cocktail, pineapple, cherries). Chop pecans.
In a large bowl, combine sour cream, coconut, mini marshmallows, oranges, fruit cocktail, pineapple, cherries, and pecans. Mix until well-combined. Fold in frozen whipped topping until the salad has fully incorporated.
Taste and add sugar if you'd like it sweeter.
Refrigerate for at least one hour prior to serving. Garnish with additional pecans + cherries, if desired.
