Plant Description:

Walter’s Viburnum is a Florida native evergreen shrub or small tree that can grow to a height of 25 feet.  However, there are many cultivars available in the nursery trade with various forms such as upright, weeping, and dwarf.  ‘Whorled Class’ is a rounded, compact cultivar perfect for use as a small hedge, foundation planting, or accent plant around trees.  Small white clusters of flowers bloom most heavily in spring, but the whorled leaf arrangement is what gives this cultivar its name, having 3 leaves growing per node along the stems.
