Popcorn Japanese snowball bush viburnum is named for its abundance of popcorn-like clusters of bright white sterile flowers that almost overwhelm the foliage in May. This cultivar has a dense, rounded habit. The foliage is dark green and turns burgundy in fall.
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.
