1. Over medium heat, bring sugar, butter, evaporated milk, marshmallow fluff and salt to a full boil in a large heavy-bottom saucepan. Once it reaches a boil, continue cooking and stirring for 5 minutes.
2. Remove from heat and add DOVE® Chocolate and stir until smooth. Pour into a foil-lined and greased pan. Refrigerate until set; at least 1 hour or overnight.
3. Divide vanilla frosting between 3 bowls, tint yellow, blue and red. Spoon frostings into three separate resealable plastic bags. Snip small corners and set aside.
4. Using cookie cutters, press out shapes from fudge. Insert wooden skewers into the sides of the flowers. Pipe frosting around flowers and decorate with M&M'S® Brand Chocolate Candies and M&M'S® Brand MINIS®. Insert skewers into an oasis filled window box or flowerpots.
