Maqui berry or Chilean wineberry has recently been named as a 'superfood'. It is very high in antioxidants and anthocyanins. The berries have been used as a traditional food in its native Chile for a very long time. The tree is fast growing, to 4m high, and tolerant of frost and some wind. They prefer well drained soils and moderate to full sun. The plants are dioecious [male or female] and have been raised from seed, so you will need to plant at least 3 to have a good chance of getting both male and female.
