Highly valued in Europe for both its ornamental value and nutritious fruit, Aronia's abundant clusters of showy white flowers in the spring are followed in the fall by large, jet-black berries and brilliant fire-red foliage. A small shrub seldom growing over 6 feet in height, Aronia is not bothered by pests or diseases. The large blueberry-size fruit is used to make nutritious juice and natural food coloring rich in anthocyanins. Aronia is hardy to minus 40°F (USDA Zone 3).
