In a blender or food processor add cream cheese, sour cream and condensed milk. Puree until smooth.
Wash fresh blueberries and pour few blueberries in each popsicle container.
Fill up the popsicle container with the cream cheese mixture, up to 3/4 of the container.
Return the rest of the cream cheese mixture onto a blender base. Add fresh blueberries and wild blueberries, then blend until smooth.
Pour the rest of the cream cheese blueberry (purple) mixture into popsicle molds, until the top. Add wooden sticks and close it with the cover, if your mold has it.
Then freeze until solid (it takes abour 3-4 hours or overnight).
