Ironclad siebold viburnum has an upright habit and approaches the size of a small tree. White flowers in May give way to red to black fruits; fall foliage is burgundy.

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.
