The nannyberry viburnum can be a large multi-stemmed shrub or trained with a single stem as a small tree.  In May it produces abundant white flowers. These give way to fruit that change from pink/rose to blue/black fruits with multiple colors persisting at the same time.

Viburnums are a versatile genus of multi-stemmed shrubs that are well suited to the home landscape due to their range of sizes and cultural adaptability. Some viburnums are noted for their fragrant flowers; most bear small fruit that may add visual interest. Many viburnums have attractive fall color. There are over 100 different varieties of viburnum at the Chicago Botanic Garden.
