Additional comments: In the Phoenix area, sandankwa viburnum is an old-fashioned, serviceable landscape shrub for historic, mesic landscape design motifs. It is quite rare to find today in the local nursery trade and was used in Phoenix landscaping more during the early to mid 20th century when flood irrigation was the most common way to irrigate landscape gardens.

A broader perspective: Viburnum is a very diverse genus containing a number of popular landscape plants grown in landscapes gardens across the United States in regions with a more temperate and humid climate (kinda like everywhere in the United States except the American desert southwest).
