The 'Northsky' blueberry is a very cold-hardy, compact dwarf shrub (Zone 3) known for its ornamental value, producing small, sweet, mid-season berries, white-pink flowers, and vibrant red fall foliage, ideal for small gardens or containers, but requires acidic soil and benefits from cross-pollination for best yields. Developed by the University of Minnesota, it's an excellent choice for northern gardeners seeking a flavorful, low-maintenance, antioxidant-rich fruit.
