In a medium bowl, mix the blueberries with the sugar and vinegar. Let macerate at room temperature for 1 hour, stirring occasionally.
Preheat the oven to 200°. Spread the blueberries on a parchment paper–lined baking sheet and bake for 1 hour and 30 minutes, stirring occasionally, until thickened but still moist. Let cool.
In a blender, combine all of the ingredients, season with salt and puree until smooth. Strain the soup through a fine sieve into a large bowl. Cover and refrigerate for about 2 hours, until cold.
In a blender, combine the oil and herbs and puree until smooth. In a sieve set over a small bowl, strain the oil through a coffee filter or a double layer of cheesecloth.
In a medium bowl, toss the fennel and cucumber with the vinegar, sugar and salt. Let stand for 3 minutes. Add 1 tablespoon of the sweet herb oil; toss to coat.
Divide the blueberries into bowls and top with the fennel-cucumber garnish. Pour the soup around the bowl. Drizzle with some of the remaining sweet herb oil, top with fennel pollen and mint or anise hyssop flowers and serve.
The soup and sweet herb oil can be refrigerated separately overnight.
