Step 1Hull the strawberries and dice them into 1/2-inch pieces. Set aside.
Step 2Peel and dice the pineapple into 1/2-inch pieces. Using a sharp paring knife, peel and section the oranges and grapefruit, reserving the juice and removing the white pith and the membranes between the sections. Slice sections in half. Place the pineapple, oranges and grapefruit into a bowl. Add the juice to the syrup, pour it over the fruit and stir slightly. Chill for 30 minutes.
Step 3Just before serving, peel and slice the banana into 1/2-inch rounds. Add the strawberries and banana to the bowl of fruit and stir once. Arrange the fruit in individual glass serving bowls. Garnish each serving with the mint and nasturtiums.
