These trees earn their keep in a northern climate, and provide interest in all four seasons. The white flowers are very showy in spring, followed by large clusters of bright red berries in summer. By autumn, the leaves turn a bright red-orange and hide the berries. After the leaves drop off in winter, the berries stay on the tree and reappear to provide colour until spring. Birds, particularly bohemian waxwings, feed on the berries during winter. The coppery bark also adds interest.
