Oh, these are wonderful companions, indeed! You will find that they provide a ground cover, and competition at the soil level that will be beneficial to the blueberries.
They can also benefit from planting peas or beans near or around to provide a boost of nitrogen to the soil. Just plant them behind everything or off to the side. They will leach nitrogen into the soil and help feed the blueberries.
