The leathery leaves grow 8 to 10 inches in diameter, with a hint of red.They have red veining, new growth has a bronzy-red tint, and some leaves will turn completely red in winter before they fall off. In late summer female shrubs produce clusters of fruit that resemble grapes (hence the plant's name) that start out green and ripen to purple. When ripe, the fruit is very sweet, providing tasty treats for people, birds and squirrels. You can make a delicious jelly or wine from them as well.
