Purple Chokeberry. A large fruited form of this very hardy N American deciduous shrub, reaching 2m tall, being a hybrid between A. arbutifolia and A. melanocarpa. Grown equally for its bunches of purple-black fruit in autumn, which contain very high levels of polyphenols/antioxidants, and the arresting scarlet and burgundy autumn leaf colour. Fruit are tart when raw but superb cooked or used in jams etc. Not for shallow chalk, but otherwise easy in most soils in sun or semi-shade.
