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