It typically grows upright with multiple stems, reaching a height of around 5 to 8 feet (1.5 to 2.5 meters) at maturity. The foliage consists of oval-shaped, serrated green leaves that turn shades of orange and red in the fall, providing beautiful autumn interest. In spring, delicate clusters of white flowers appear, which eventually develop into small, dark purple berries resembling blueberries.
