Place the cream and sugar into the bowl of a stand mixer with the whisk attachment and whip until stiff peaks are formed. Add the sour cream and whisk to combine. Add the marshmallows, orange, pineapple, coconut, pecans and cherries and stir to combine. Transfer to a glass serving bowl, cover and place in the refrigerator for 2 hours before serving.
