Michael Dirr’s Plants has a nice article on different types of Viburnums called “Viburnums for American Gardens: Abbreviated Discussion“. This is a great article describing different viburnums used in landscaping. Viburnums make great Bonsai trees if you can find one with an interesting trunk. The leaves and internodes can be reduced using by using my Viburnum Leaf/Internode Reduction Technique. I have added the article to the Viburnum Bonsai page under Deciduous Bonsai and Bonsai Tree Information pages.
